VT02N : Need to make a Field on Screen Required.

Question

Hi All,
I have a situation where in i need to change the "Ship-to-party" field on the "Select Outbound Deliveries" screen to a required field.
This screen is the one that pops up when the Deliveries Button is clicked on the initial screen.
Is there any Exit or a Search Help that can be used for this.
Thanks in advance..!
