An activity can be thought of as any action for which an entry can be made on a calendar. An activity has time dimensions (start time, stop time, due date, and duration) that help determine when the action occurred or will occur. Activities also contain data that helps determine what action the activity represents, for example, subject and description. An activity can be opened, canceled, or completed. The completed status of an activity will have several sub-status values associated with it to clarify the way that the activity was completed.
Activity entities can only be owned by a user or team, they can’t be owned by an organization.

You can create new custom activity entities. For example you might create a custom activity entity to record instant message communications. Creating an activity entity is different from creating a non-activity entity because you don’t specify a primary field. All activity entities have a Primary Field set to Subject and other common fields that are defined by the Activity entity. This allows all types of activities to be shown in a view where just the common fields are displayed.
To create a custom activity entity, select Define as an activity entity. After you select this, you’ll see that Display in Activity Menus is selected. This setting allows people to choose to create this type of activity in the activity menus. This isn’t selected for activities that are typically associated with specific events and created behind using code or by a workflow. After you save the entity, you can’t change these settings.
