A requirement for the reconciliation process between the invoice and purchase order is to have the purchase order item on the billing document. To meet the requirement to include purchase order item, the values must be added on the Sales Document line item. An extension will need to be developed to add the PO Item when the Billing Request is saved.
Due to the cardinality of the Service Materials and Purchase Orders and Service Orders, there will only be one line item per Purchase Order. Therefore the line item value will always be u201C10u201D.
The Logic is to populate the field, POSEX, on the billing request line item with u201C10u201D when the request is saved during the DP95 run.
Sales Document Types for which this extension pertains are ZSCR and ZSDR.
