Within our PO process, I created a PO which references a contract. Both have a Validy Period Start and End set up in customizing and filled in. But my problem is that I can still enter a Goods Receipt in MIGO to that PO, after validity has ended. I've set up in customizing the system message 06-041 as Error, and I've put in Screen Layout the checkbox 'GR message' for both PO and Contract.
Is there a way to block the GR threw IMG outside of the Validity Period ?
Thx in advance,
