About Objects in Lookup Fields

The Object Name selected in a lookup field can be Custom Objects or System Objects, or any of the following:

• Users

• Users associated with records in the object become clickable
• When clicked, the associated User record is opened

• Documents

• Documents associated with records in the object become clickable
• When clicked, the associated Document record is opened

• Templates

• Use this option when using the sendEmailUsingTemplate call in the Java API. This allows the Template Record Identifier to be fetched programmatically for Campaigns, which saves time (instead of hardcoding record id).
