3799927 - External Processing Operation in Production Order — No Purchase Requisition Created on Order Release, or Goods Receipt for External Operation Not Possible

A production order contains one or more external processing operations (routing operations with control key PP03 or a similar externally-processed control key). After releasing the production order in T-Code CO02 or CO01, one of the following problems is observed:

1. No purchase requisition is created — After order release, T-Code ME2O (External Processing: Overview) shows no purchase requisition for the external operation, and T-Code ME21N (Create PO) cannot find a PR to reference. The production order shows the external operation with status "not released" for purchasing.
2. Purchase requisition exists but cannot be converted to a purchase order — T-Code ME2O shows the PR but T-Code ME59N (Automatic PO Creation) does not create a PO, or a source list error is displayed.
3. Goods receipt for the external operation is not possible — After the external vendor completes the work and a PO exists, the GR cannot be posted, or the operation remains in "partially confirmed" (PMCO) status even after posting.
4. Confirmation of external operation in T-Code CO11N fails — The system does not allow confirming the external processing operation in the normal operation confirmation transaction.
