SNP Planning book- Pop up while deleting Production Planned KF values

Hi Experts,

Whenever a user is trying to delete a planned Order(from Production Planned KF) in the SNP interactive planning book, a pop up window comes, where the user is asked to select one of the 'Admissible sources of supply'(basically the system gives an option to chose from the PDS.

When deleting a planned order they should not be forced to do that since there will no longer be a planned order.

This makes sense while creating planned orders but doesnt seem to make much sense while deleting them.

Any comments/suggestions are most welcome.

Thanks

PSq.
