SAP is allowing the creation of PO's for C.codes for non extended vendors
SAP is allowing the creation of purchase orders for company codes to which the vendor has not been extended. An example is PO 4500XXYYZZ for vendor number 9010577. The PO was created for company code 1111, but the vendor is not extended to company code 1111.
Please suggest how to avoid the above transaction by throwing an error.
