Hello,
I am curious about a few things when it comes to Activity type Entities, Activities under Communication and Collaborations section, and creating custom entities.
I have some requirements for some new features in an application of mine. I am unsure to use an OOB entity and customize it, or create a new one. I have been playing around with some things and know that when you create a new entity with "Define as an activity entity" you then cannot add the "Activities" option under Communication and Collaboration.
I am in a pickle because I am playing with using the "Letter" entity, which is Defined as an activity entity, BUT I also want this option to be available in the "Regarding" fields of another custom entity.
I've read that the "Activities" option under Communication and Collaboration is necessary for those type of records to be available in the Regarding field of other entities.
There is an OOB entity for Campaign Activity, it has BOTH "Define as activity" AND Activities" option under Communication and Collaboration:
Any idea if there is a custom way to do this for a new entity? Edit existing entity to enable this?
