A package is a collection of objects, applications, and other platform resources.

1 About Packages

Packaging provides the ability to deploy fully-featured solutions with seamless distribution to platform Tenants. (Tenants who have installed such a package are deemed to be Package Subscribers. The user who does the installation is called the Package Installer.)

Publishers can bundle all elements of the AgileApps Cloud platform into custom Packages, which deliver customized business solutions to Package Subscribers.

Tenants can create and publish packages for internal use, or for wider distribution.

How it Works

1. Platform elements and applications are Packaged and Published.
2. They can then be submitted for approval
3. Approved packages become part of the Application Catalog
4. Tenants can then install the published package.

Alternatively:

• A publisher can give tenants a link they can use to install the package, without having to put it into the catalog first.

• ISVs can do an automated Mass Deployment of Packages to Tenants

1.1 Package Items

Platform elements that are included in a Package are known as package items.

This page details when items are included in the package, when they are installed in the target system, and when old items that have been removed from the source system are deleted from the target system, as well.

The information provided here is the foundation for the companion article: Choosing a Deployment Strategy for Development Systems

1.1.1 Standard Dependencies

When an item is selected for packaging, dependent elements are automatically included. Items that are related, but upon which the selected item does not actually depend are excluded by default--although they can generally be selected manually, if desired.

Platform Element	Dependent Elements
Application	Includes Application settings Includes all Custom Objects used in the application, along with their dependencies (see below) Includes all Global Picklists referenced by a field in an included object Includes all Classes that are referenced by a Business Rule or Macro Includes Dashboards that are visible to all, a Role, or a Team. (Does not include private dashboards.) Includes all Pages used in Dashboards, Web Tabs, and Sites, as well as all Pages invoked by an Action Button Includes all Application Reports that are visible to all or that are visible to an application Role. Includes all Roles used in the application Includes all Sites defined in the application Includes role-based Tab Preferences for objects Includes all Team definitions that are referenced in a Business Rule, Process, or Macro Includes role-based View Preferences for objects Includes all Web Services that are used in a Process, an External Lookup, an External Data Source, or a Business Rule Includes all Web Tabs defined in the application
Objects (Custom Objects and System Objects)	Includes all object settings and object relationships, including Record Locators Includes all objects that are the target of a Lookup Note: Does not automatically include objects that have a Lookup to the current object. If such Related Objects are not included in the package, any Related Information sections defined in object forms are automatically removed. Includes all objects that are encompassed by a Rollup Summary Field Includes Business Rules Includes Document Templates Includes External Data Source definitions Includes Forms, Layout Rules, Form Scripts, and Custom Form Actions Includes Fields and Field Scripts Includes Indexes Includes Macros Includes Processes Includes Validations Includes Web Forms Excludes Reports Reports can be individually selected. Reports on an object are not automatically included. Excludes data Data is not included automatically. Java code can be written to create Package Data classes that add selected records during packaging, and that take the records out when the package is installed.
Object data and other data (Package Data)
Classes (includes user-created classes)
Mapping Profiles
Pages
Reports
Sites	Includes Pages
Static Resources
Teams
Team Data Sharing Policies	Includes Teams and Roles involved Includes Child Teams if the Include Child Teams option is selected for that team
Template
Template Access URL	Includes Template. Includes Application. For more information about Templates, see How to Create a Custom User Interface (CUI).

1.1.2 Special Dependencies

When the following elements are added to a package, the listed items are added as dependencies:

Team Data Sharing Policies

Roles and Teams included as dependencies

• If the Include Child Teams checkbox is enabled, the child teams of the selected teams in the Data Sharing Policy are added as dependencies

Objects in a Master-Detail relationship

Note: The "Master-Detail relationship" option on a Lookup field has been deprecated. This section is provided for legacy objects that have a Lookup field for which that option has been selected. Learn more: Master-Detail relationships If a Detail object is added to a Package, the Master object is added (automatically) as a dependent object If a Master object is added to a Package and if that Master object includes any Rollup Summary Fields, then the Detail object is added (automatically) as a dependent object When a Tenant installs a Package, the Rollup Summary Fields limit defined in Manage Tenant Capabilities is honored If the limit is exceeded, the installation process will stop and cannot proceed In order to complete the installation, delete existing Rollup Summary Fields to reduce the total number to within the defined limit After packaging, do not add or remove any Master-Detail relationships; doing so may cause unexpected results and/or loss of data

Template Access URL

Templates and Application included as dependencies. For more information about Templates, see How to Create a Custom User Interface (CUI).

1.1.3 Items that are Never Packaged

These platform elements are never added to a package. Customizations made by the subscriber remain intact.

• Access Profiles
• Knowledge Base articles
• Knowledge Base categories
• SLAs

1.1.4 How Package Items are Applied

The principles that follow summarize the behavior of package items at installation time. Detailed tables list the behavior for individual items, following the summary.

1.1.4.1 Principles

• New items in the Package are added to the subscriber's system, while items with the same ID are replaced, or updated.

Note:

All aspects of an object (fields and forms, validations, and so on) are given a Globally Unique ID or GUID. Those IDs are preserved when the package is installed, which allows existing items to be replaced while new items are added. (When the overwrite option is chosen, items on the target system that do not have a matching GUID in the package are deleted.)

• If the subscriber created a new platform element with the same name as an item included in the package, the subscriber gets an error. (The error occurs immediately after they select the package. Installation is not allowed to proceed.)
• With few exceptions, modified items in the Package replace the versions that came from a previous Package.
  The exceptions are:

• Global Picklists -- Subscribers are expected to have added items and modified labels, so they are left intact.
• Email Templates and Quick Text -- These items are overwritten only if Overwrite Previous Package was selected by the publisher.
• Roles -- During installation, the subscriber has the option of merging or overwriting roles that are included in the package.

Note: Items that were added to the target system are never deleted. Items are deleted only when: (1) They were previously installed from the source system, (2) They were subsequently removed from that system, and (3) The Overwrite Previous Package option was chosen when the package was created.

1.1.4.2 Object Aspects

** View definitions are included only when they are visible to all, or to an included Role. Private views are not included.

*** Web Forms on objects other than Cases can contain two kinds of email templates--an auto-response template that

is sent to the submitter, and a notification template that tells internal users about new records. Unlike other email templates, they are always overwritten.

1.1.4.3 Application Elements

This table describes the behavior of other platform elements that go into an application.

Note: Include the Users Object in the package whenever fields or business rules in the package has references to the Users object. Include the Users Object in the package whenever record visibility criteria for an object in the package has references to user custom field.

1.1.4.4 System Elements

This section describes important system-object and system-configuration items:

System Element	Included when		Installed when
	Selected	or if Referenced by	Added if New	Updated	Deleted if Old
Access Profiles	not included
Business Hours Calendars		Process	✔	N	N
Email Channel settings	not included
LDAP Configuration	not included

Service Portal settings	not included
Scheduled Jobs **	not included
Single Sign-On settings	not included

* Potentially valuable for an on-premise installation that wants to back up their primary admin tenancy.

** Scheduled Rules, on the other hand, are included, along with other Business Rules.

1.2 Package Considerations

• To publish an application, include it as part of a Package, and then publish the package. Application components are automatically added to the package.

• The components contained in a locked package cannot be modified. So new fields cannot be added to an object, for example, and existing fields cannot be modified.

• The components of an unlocked can be modified, with both additions and changes. Additions are preserved during an upgrade. Changes are overwritten. For example:

• If a Rule is added to a packaged object after installation, that Rule is preserved.
• If the packaged object contains a Rule, and that Rule is modified after installation, the modifications are overwritten by the next upgrade (assuming that the new version still contains that Rule).
• Similarly for additions and modifications to Forms, Validations, and other aspects of the packaged object.

Notes:

• If a field expected by such an addition no longer exists, an error will occur when the field is referenced.
• If the field is "retired" rather than deleted (by changing it's label and using the old label on a different field), then an added item like a Rule that uses the field would still work, but could deliver inaccurate results.

• Given those considerations, anyone who is in a role which allows them to modify an unlocked package needs to know what the package contains and know that, while additions will be preserved, any changes will be overwritten at the next upgrade.

• When you add an item like a field to an object which is part of an installed package (and which might later be upgraded), a unique identifying number is appended--so there is no chance that a future upgrade will overwrite your addition.

Exception: If you are in a development Sandbox, working on a package imported from another Sandbox, your additions are seamless. No identifiers are appended.

• The names of Fields and Objects created cannot match the name of any Package element. If there is a conflict, Package installation will fail. To succeed, either the Publisher or Subscriber will need to rename the conflicting item(s).

• To include Package Data, you must Create a Data Handler class and then Configure Package Data, so that data can be selected as part of the packaging process.
• Permissions Considerations:
  • When roles are included in a package:
    • Any permissions they contain for objects present in the package are carried over to the subscriber's instance of the platform.
    • Any administrative permissions they define are also carried over.
    • No other permissions are carried over.
  • When a user installs a package that contains role definitions:
    • The user is prompted to assign users to the new roles.
    • If the user is re-installing, the user can choose to override, ignore, or merge permissions for the new roles. (Installation documentation should instruct the user on the preferred course of action.) The choices are:
    • Override - Overwrite the existing role definition.
    • Ignore - Leave the existing role untouched.
    • Merge (the default) - form a union of existing role permissions and the role permissions defined in the package.
  • If a package does not include any Roles:
    • The package installer is shown a list of existing Roles defined in the tenancy.
    • The installer can select the Roles which will have access to the objects included in the package.
    • All selected roles get Create, Delete, and View permissions for records owned by the user, and View permissions for records owned by other team members.

• When installing a Package that includes Sites, these fields are automatically populated:

• Login As User for Unauthenticated Access field is populated as the user who is logged in
• User Web Adress is BLANK

Note: When a package is reinstalled, these fields retain the values configured by the Package Subscriber.

1.3 Package Limitations

These package items have the following limitations:

Report

Only reports in folders that are "Visible to Everyone" or "Visible to {someRole}" can be added to a package. Reports in folders that that are visible to specific users or teams cannot be added. (The Role needs to be added to the package, as well, unless it is sure to be on the installer's system, for example by virtue of being in a package that this one depends on.)
Learn more: About Report Folders.

Custom Object Views

Only views with the "Visible to Everyone" control, visible to selected roles, or visible to selected teams can be added to a package.

Users

Not included in packages, and must be re-created in the new instance.

Note: Up to 5 translated languages can be included while packaging. Exceeding 5 is known to cause performance concerns with package installation.

2 Working with Packages

Users that have the Manage Packages permission can create, modify or delete Packages

2.1 Package Attributes

When you open a package, some sections always appear. Others appear only when the package is published:

2.1.1 Package Information

Basic information about the package, including:

• Package ID - This ID is the package record ID. It's used when downloading a package, and in APIs that manipulate package contents.

2.1.2 Installation Details

This section appears only when the package has been published. It contains:

• Installation Link - The link subscribers can use to install the package.

Important: The value that appears in the URL's id query parameter is the package installation ID. That value is used in APIs that deploy and install packages.

2.1.3 Items

The list of items that were chosen for inclusion in the package. Generally consists of an application, but may also consist of objects, classes, and other application elements.

2.1.4 Item Dependencies

Objects, classes, and other application elements that are required by the items that were chosen.

2.1.5 Package Dependencies

Other packages that are required for this package to run.

2.1.6 Revision Details

A list of up to five of the most recent package versions. Each item in the list displays:

Version number

The number assigned to the package when published.

Version notes

Any notes that were entered for the package when published.

Publication Date

The date and time the package was published.

Catalog Status

• Submitted - The package was submitted for inclusion in the Service Provider's catalog, but has not yet been approved.
• Approved - The package was approved by the Service Provider. It should now appear in the Service Provider's catalog. (That is a two-step process, so it is normal for there to be a small delay between approval and appearance in the catalog.)

Considerations

• Only the most recent 5 versions are shown in the list, unless a version was submitted for inclusion in the Service Provider's catalog. That version is always retained in the list, until supplanted by a newer version.
• Only one version of a package appears in the catalog.
• A new version of a package is created does not replace the existing version in the catalog until the new version has been submitted and approved.
• In the rare case that a new version of package is published before a submitted version is approved, the status of the original version changes from Submitted to (none). (In the Catalog Information page, click [Save and Submit] to send the new version for approval.)
• If a submission is disapproved by the Service Provider, an email is sent to the submitter, and the Catalog Status reverts from Submitted back to (none).
• When a submission is approved, package revisions and edits to the catalog information do not affect the existing catalog entry, until they are submitted and approved.
• When a package is re-published, the aggregate user rating for the previous version is transferred to the new one.

2.2 Create a Package

1. Go to > Administration > Account Management > Packages
2. Click [New Package] and enter the following information:

   Name

   Name of the Package (this name appears in the Catalog)

   Description

   Description of the Package

   Locked

   To Lock the package, click the checkbox icon

   Learn more About Locked and Unlocked Packages

3. Click [Save]

2.3 Add Items to a Package

1. In the Related Information section, click [Add Item] to select items for the package

2. Under Item Type choose from the list of things you can include, as described previously under Package Items

Note:
If Package Data has been configured, the Data Handlers for configured objects will also appear in this list. (More on that subject in a moment.)

3. Click the checkbox icon for each item you want to include in the package

4. Click [Add to Package]

Continue adding until the package contains the desired items.

Note: Before including them in the package, any Default Roles and the default team (My Team) should be renamed. Otherwise, duplicate names/teams are created in the installer's domain, which could be confusing.

2.3.1 Adding Data to a Package

To add Package Data:

1. Choose Add Item > Item Type, and choose the item that corresponds to the data in that object.
   For example, Zip Map Data.
   A pane appears that lets you specify the data elements to include.
2. When the data-item selection appears, select All at the top left of the pane to add everything, or else select and deselect individual data items.
3. Click [Add to Package]

Note: It is possible for there to be package data that is not part of an object. When object-data is included, it is also possible that the target-object is expected to exist on the Package Installer's system. What happens is up to the Data Handler, so object definitions are not automatically included along with object data.

2.3.2 Reviewing Item Dependencies

In the Item Dependencies section, review the list of specified Package Items, along with the dependent items they caused to be included.

For example, if a report is added to a package, the Objects that are used as the basis for that report and the Database View the combines them will be added to the package as dependent items.

2.4 Specify Package Dependencies

A package can be dependent on specific versions of other packages.

Click the [Add Package Dependencies] button to add a dependency, and select the package version:

• If the specified package is published in the current tenancy, the list of versions for that package is displayed.
• If the specified package was installed, the currently installed version is displayed.

Considerations:

• If package B is listed as a dependency for package A, then package B cannot be deleted as long as package A is installed.
• Objects are only added to a package if they are not already present in a package that is listed as a dependency.

2.5 Remove an Item from a Package

1. In the Related Information section of a Package, navigate to the item of interest
2. Click the Remove link to delete an item

   When an item is deleted, it is automatically removed from the package along with its dependencies, for example:

   • If the report is deleted, the report and the dependencies are removed from the package as well

2.6 Publish a Package

Publish

2.6.1 Editing Catalog Information

When a package is published, the [Edit Catalog Info] button is enabled. Information defined here is used to describe the package in an application catalog, or Community Marketplace.

Note: If the Community Marketplace has been enabled by the Service Provider, all of the information provided on this page is displayed. Otherwise, only the description and catalog icon are used.

To edit a catalog entry:

1. Click [Edit Catalog Info] to specify additional information that should appear for the package when it is listed in a catalog.
2. Fill in the Catalog Settings.
3. Click [Save and Preview] to see a formatted version of the catalog entry.
   • This option appears only if Community Marketplace has been enabled by the Service Provider.
   • Browser popups must be enabled to display the generated page.

4. Click [Save and Close] to save work in progress.

5. Click [Save and Submit] to submit the package for inclusion in the Service Provider's catalog.
   • Click through the user agreement to finish the submission process.
   • An email is sent to the Service Provider to let them know there is a new package in their approval queue.
   • In return, you get an email when the submission is approved (or rejected).
   • The submission status is also displayed in the package's Revision Details.

2.7 Download a Package

A package you create can also be downloaded from the platform to your system as a zip file. Others can then use the file to install the package.

The Install Package from File option is enabled by your Service Provider. The default single sign-on setting on on-premises installation is Off. The default single sign-on setting on the cloud is On. (Contact Support to make changes.)

To download a package:

1. Publish the package, if it has not already been published.
   The Installation Details section appears.
2. In the Installation Details section, click [Download Package].
3. Save the file to your system from the browser.

For convenience, you can then rename the file to something appropriate.

2.8 Deploy a Package

Deploying a package automatically upgrades local Package Subscribers (tenants in the same platform instance who have installed the package).

The Mass Deployment of Packages to Tenants option is enabled by your Service Provider. The default single sign-on setting on on-premises installation is Off . The default single sign-on setting on the cloud is Off . (Contact Support to make changes.)

When you deploy a package, you can chose to automatically upgrade:

• All (local) tenants who have installed the package
• Selected (local) tenants who have installed the package

To deploy a Package:

1. Create a Package, and add items to it.
2. Click [Publish]
   The zip file and Installation Link are created.
3. Click [Deploy].
4. Specify which tenants to upgrade.
5. Specify a deployment time, or chose Immediate.
6. Click [Deploy] again to act on your selections.

Learn more: Package Approval or Rejection

2.9 Distribute a Package to Remote Tenants

When a Package is Published, it can be downloaded from a browser. An Installation Link is automatically created that can be used to distribute the package.

To Give the Download URL to Remote Tenants:

1. Click > Administration > Account Management > Packages
2. Click the link of the package of interest
3. In the Installation Details section, find the Installation Link
4. Copy the Installation Link URL and paste it into a web page or send it in an email.

Users with valid accounts can then download the package and install the application by following this procedure, which should be provided in the installation instructions:

1. Paste the Installation Link URL into a web browser to visit the installation page.
2. Click the [Install] button to install the package.
   (A valid user account is required to Login.)

2.10 Delete a Package

When a Package is deleted, the Teams and Roles are not deleted

• To remove the Teams or Roles from an installed Package, delete the Teams or Roles manually

To delete a package:

1. Click > Administration > Account Management > Packages
2. Click the package name to open the package of interest
3. Click the [Delete] button to delete the package

If a Package is deleted and that package has been installed, or if the package is being used by any other package, then any items or dependent items in the package are retained, and are not deleted.

3 Installing Packages

3.1 About Package Installation

The installation page displays:

• Package version notes
• Any messages generated by the platform (for example, messages that result from version conflicts)
• Options for dealing with Role definitions in the package, given that those roles may have been modified in the customer tenancy:

• Override existing roles - Replace current role definitions with the roles defined in the package.
• Ignore package roles - Don't import role definitions from the package. (Could be problematic if new roles were created.)
• Merge roles - Merges new roles and privileges added by the package provider into the current roles, with any privileges that may have been added by the installer.

• A list of items contained in the package

3.1.1 Other Considerations

• Names of Custom Objects, System Objects, Fields, Classes, and Pages are validated for uniqueness
• If the Package Subscriber has created an item with the same name as an item in the package, the installation will fail. In order for package installation to succeed, the Package Subscriber must change the name of the Field or Object that is in conflict.
• Role and Team names are not validated for uniqueness
• If a Role in the package has the same name as any of the Default Roles, a duplicate role is created.
• If a Team in the package has the name as the default team (My Team), a duplicate team is created.

(Package providers should rename those default roles and teams before including them in the package.)

• If a child team is included in the package, it is attached to the first top-level team in the installer's instance.

3.2 About Locked and Unlocked Packages

In an Unlocked package, objects and data can be modified and deleted by the package Subscriber.

In a Locked package, in contrast:

• Data can be modified and deleted, but objects (including global picklists) can only be modified to the extent that permission to do so has been granted by their respective Object Packaging Options.
• Any classes, pages, and any other form of executable java code contained in the package cannot be viewed, edited, or deleted by the Package Subscriber.

Considerations

• The Publisher can change an Unlocked package to a Locked package
• A Locked package cannot be changed to an Unlocked package
• The Object Packaging Options apply only to Locked packages

Notes

• Roles control the user's ability to customize the platform
• Consider modifying roles to support best practices

3.3 Information for Package Installers

Considerations

• An installed package and any of the items it contains can be repackaged and republished.
• When installing a package upgrade or reinstalling a package, new items are added and existing items are either Merged or Overwritten, based on the Overwrite Previous Package configuration defined by the Publisher.

Overwritten

The package's version of the platform entity replaces the installed version.

All changes and additions are replaced by the package contents:

• Fields added to the installed version of an object are lost, along with changes to the object and any fields it contains.
• Rules added to an installed Rule Set or event are lost, along with changes to existing Rules.
• Similarly for other platform entities.
• Processes are overwritten, but your versions are still available, so Process Versioning can be used to revert to your customized versions.

Merged

The package's version of the platform entity is merged into the installed version.

All changes and additions are replaced by the package contents:

• Fields added to the installed version of an object are retained, but changes to object fields are overwritten.
• Rules added to an installed Rule Set or event are retained, but changes to existing Rules are overwitten.
• Similarly for other platform entities.
• Processes are overwritten, but your versions are still available, so Process Versioning can be used to revert to your customized versions.

Available actions for Locked Packages

Users cannot Edit or Delete package items, however:

• After installation, Package Subscribers can choose to Enable or Disable the following items, if the publisher has granted that permission in the Object Packaging Options:

• Validation
• Custom Form Actions
• Document Templates

Available actions for Unlocked Packages

Users can Edit or Delete package items

Considerations

• When an unlocked package is upgraded by the Publisher, local customizations made by the Package Subscriber may be overwritten.
• To signal that fact, a warning message is displayed before the upgrade: Customizations are over-written with a package upgrade

3.4 Installing from a File

A package can be downloaded to your system as a zip file and used for installation. This feature is used to migrate packages between separate instances of the platform--for example, in a development environment.

The Install Package from File option is enabled by your Service Provider. The default single sign-on setting on on-premises installation is Off. The default single sign-on setting on the cloud is On. (Contact Support to make changes.)

To install a package from a file:

1. Download the zip file that contains the package.
2. Visit > Administration > Account Management > Packages
3. Click [Install from File]
4. Use the File Chooser to select the zip file
5. Click [Next].
   The package is installed.

Warning: Do not rename the zip file after downloading it. During installation, the name of the file is validated against the file's contents.

3.5 Special Considerations for ISVs

1. ISV Admin can subscribe to own packages. (If the ISV Admin has published a package on another system, then it can be uploaded and managed as though it were created on the current platform.)
2. ISV Admin can manage items inside a locked package if it came from another platform instance.

3.6 What Happens to Modified Objects when a Package is Re-Installed?

The short answer is, "the platform does the right thing". So data is never lost without warning. The longer answer depends on the case at hand:

Publisher has added a field

The new field is added during package installation. The field value is empty in all existing records. Additional programming or manual updates are required to populate those fields with values.

Publisher has removed a field

In general, the field is not removed during package installation. It remains in the Subscriber's object. Record data stored in that field is unaffected.

Exception: If the package was locked and the publisher has chosen to overwrite the previous version when re-publishing, then the field is removed during package installation.

Subscriber has added a field

The field remains in the object, and stored data is unaffected.

Subscriber has removed a field

The field is added back when the package is reinstalled.

Note: The one situation that does not arise is that of a renamed field. Fields can be added and removed, but they cannot be renamed. (The field label can change, but not its name.) In effect, the field name is a unique index, so the platform always knows what to do.
