You trigger the consumption of the components from SAP ERP. One way is to trigger a goods issue posting with reference to the production order. With the confirmation of the production order, it is possible in the SAP ERP system to generate a consumption posting for backflushing. In both cases, an outbound delivery is then created and replicated to SAP EWM. The delivery is not relevant for picking in SAP EWM and, with the correct settings, the system posts a goods issue immediately on creating this delivery.
Note
As with other documents, there is no outbound delivery request in an SAP S/4HANA embedded EWM.
