We have raised one PR and it is gone under Release Strategy and it is released. After final release of the PR again user added one more item in that PR though ME52N without the superioru2019s permission. We require PR should be in Non editable mode in ME52N for released PRs. If require to add or remove anything from the PR, it should be unrleased first and then edited again it should go through release strategy.
Go to SPRO > Materials Management > Purchasing > Purchase Requisition > Release Procedure > Procedure with Classification > Set Up Procedure with Classification > Release indicator > Here for Release indicator "2" i.e. RFQ/purchase order, assign the field selection key as "AKTA" or "ME23" i.e. Display.
