Initial Action
On the Event Handlers form, for event handlers that have multiple actions to perform, use this option to determine which action is performed first. All other actions are performed in the order in which they appear in the Event Actions grid.
If this field is blank, the system performs actions in the order in which they appear in the Event Actions grid, subject to the limitations of the action sequence.
On the Event Handler Revisions form, this field is display-only and indicates which action is set to be performed first.
