After adding a special event or fundraiser, you may notice you do not have a designation tab on the event record. On a special event record, the designation tab is missing.
This occurs when the Event allows designations on fees checkbox was not marked when the event was created. To correct this issue:
In the Tasks menu of the event record, select Edit event.
Mark the checkbox for Event allows designations on fees.
Note: If there are existing registrations on the event, the checkbox will be grayed out. The registrations (and applied payments, if entered) will need to be deleted in order to make this change to the event. The registrations can be reentered after the checkbox is marked.
