Online shop: Cancelation process for third-party processing in SAP Retail

The order quantity changes/cancelations should be changed by customer service and communicated to SAP via customer service's front end. The communication from the front end that an order quantity change or a cancelation is to be executed in SAP Retail only takes place once this has been clarified by all parties (customer, supplier) via customer service. The customer order therefore needs to be adapted at the item and/or quantity level (if this is possible in the same way as for the supplier orders). The IDoc message type PORDCH (change purchase order) is used in the incoming area (from the front end) for order quantity changes or cancelations. This IDoc message type enables quantity changes and cancelations (setting a delete indicator) in a relatively easy way and with reduced IDoc scope. These purchase order changes also need to be forwarded to the customer order item; i.e. for quantity changes, the order quantity has to be adapted and for cancelations, the order item has to be refused.
