About Objects in Lookup Fields
From AgileApps Support Wiki
Any Object can be the target of a Lookup, as well as:
-
- Users associated with records in the object become clickable
- When clicked, the associated User record is opened
- A lookup field that targets the Team object can be clicked
- When clicked, the corresponding Team record is opened
- Use this option when using the sendEmailUsingTemplate call in the Java API. This allows the Template Record Id to be fetched programmatically, which saves time (instead of hardcoding record id).
