To change the end date of an assignment, what action must first be performed?

To change the end date of an assignment, the action that must first be performed is to either curtail or extend the assignment. This is essential because altering the end date involves modifying the current time parameters set for that assignment. The curtail or extend action is the method utilized to officially adjust these parameters, allowing for the new date to be recognized by the system.

After this initial step is taken, other processes may follow, such as submitting an update or obtaining necessary approvals. However, these actions cannot occur until the curtail or extend action has been executed, as it directly addresses the need to revise the assignment's timeline. Therefore, transferring from one date to another starts with this critical action.
