Do not use loop@ under the following circumstances:

•If you want the user to manually select which sub-object's or related object's information to include in the generated document, you should use filter@. For details, see filter@ Merge Fields for User-selected Related or Sub-objects.

If you want the user to manually select a sub-object or related object only when more than one is found, you should also use filter@.

•If you want to retrieve the address (or other sub-object) of the contact in a contact-centric project, you cannot use loop@. Instead, it is recommended to retrieve the default address of that contact, using a basic merge field that is mapped to an object field.

•If you want to get a sub-object that is set as "default," such as the default category, default address, or default phone number, you can do this with a basic merge field or an auto-mapped merge field, instead of a loop@ merge field. For examples, see Automatically Mapped System Fields.

•If you want to get the main assignee's name, you can do this with a basic merge field or with an automatically mapped field. See Automatically Mapped System Fields.
