How to delete a PO in SRM
one PO has been created in SRM and replicated to the backend.
I would ask how can we delete this PO (because the data was wrong), should we delete the PO in SRM side or in the backend?
If you are using extended classic scenario you can simply delete the line items in the PO within SRM. This will replicate the appropriate changes in the backend.
You won't be able to change the PO in the backend as this is standard functionality.
