Multiple PO's created with 0 price for same PR

[Gaurav_Gautam]

Hello Gurus, 

One of the buyers clicked on the save button multiple times in S4HANA SSP, which caused the system to create a new PO for the same PR but with a 0 price, and it went to the supplier. How can we stop this behaviour so that once the PO is created for the full value, the system shouldn't allow duplicate PO's for the same PR, even buyer by mistake clicks on the save button. 

Thanks in advance.

Gaurav

Dear Gaurav, 

normally it is not possible to assign one PR with multiple POs unless you share the qty. 

I retested it:

Created on PR with qty of 2 pieces

Then I assigned the qty to two POs, both with one

When I try to assign it one more, I get error message.

Could you handover some screenshots to show and describe it more?

Best regards

Dennis
