Blocking

Hi All,

This issue has not been resolved in our SBO system. we can't prevent user to add good receipt PO without copy from PO. I mean the user should only make good receipt if it based on a PO. How to prevent good receipt PO posting if there is no PO number as a base document ? I would appreciate if it is store procedure since our FMS and UDF are so many used now. Pls give advice. TIA
