While making PO for particular material,earlier the PR was not mandatory.
Now automatically system is asking to put PR no.
I have already checked SPRO settings as well as OMET settings.
Everything is for 'PR NOT MANDATORY'
Suddenly what has happened,that the system is asking to put PR.
First check what is the relevant Document type and FIELDSEL. you have in SPRO-MM-PO-Define Document Types
Then go to SPRO-MM-PO-Define screen layout at document level. Select the FIELDSEL you found above and go to details REFERENCE DATA, ITEM check if purchase requisition is marked as Reqd. entry. Change if you need to.
Please revert if this is helpful.
Go with the path and make necessary changes.
SPRO-MM-Purchasing-Purchase order-Define Screen Layout at Document Level-Select ME21N-Double click on Reference data, item-here make the purchase requisition as optional entry.and save.Then create a new PO now and see the difference it will work out.
