Purchase Requisition not editable if Purchase Order exists, SAP S/4 Hana Public Cloud

[gg8]

Hi all, 

I'm trying to find a way to inhibit the possibility to edit a Purchase Requisition if a Purchase Order has already been created in reference with that PR? I'm working with SAP S/4 Hana Public Cloud! 

Does a standard configuration exist for this or must be managed through a custom logic in a BAdI?

I read in some blog that is possible to manage it through Release Strategies, in particular with Release Indicator field.. I did not find anything similar in SAP Public Cloud actually..

Can you please help?

Thank you.

Hi,
I think you can try to use BAdI MM_PUR_S4_PR_CHECK. This BAdI is designed to perform custom checks on purchase requisitions, You can use CDS View I_PurchaseRequisitionItemAPI01 and I_PurchaseOrderItemAPI01 to fetch data to check via this BAdI.
