Inventory confirmation is an important process between SAP EWM and SAP ERP, where a change in inventory in SAP EWM is synchronized with SAP ERP. Inventory changes typically occur in goods receipt and goods issue processes when stock enters or leaves the warehouse.

While the seamless integration of SAP ERP and SAP EWM ensures end-to-end stock consistency, stock inconsistencies between the systems often occur when an external WMS is connected.
