I want to recomment off the coding which prevent Subcontract PR to be changed due to reservation number ( refer to OSS note 501861 &537507 )
This function is in function group MEWQ. Can i copy the function group to ZMEWQ and then copy BAPI_REQUISITION_CHANGE to ZBAPI_REQUISITION_CHANGE to ZMEWQ, and let my program call the ZBAPI_REQUISITION_CHANGE ?
Is this the right way to do it? Please advise.
