Adding a Subtab for a Child Object


In this demonstration, you will learn how to display child object records in the work area of a parent object at runtime.

 

We will create a subtab in the trouble ticket that displays the records of the Activity child object.

 

Users will use the Activities subtab to manage activities while resolving the issue in a trouble ticket.
