To connect SAP Extended Warehouse Management (EWM) with the programmable logic controllers (PLCs) in a Material Flow System (MFS), these steps are followed:
* Activate the Link to Subsystems Using the ALE Interface on the Warehouse Number (A):
* ALE (Application Link Enabling) interface is used for integrating external systems.
* The warehouse number setup includes enabling the ALE connection to communicate with subsystems like MFS.
* Use an RFC Adapter to Connect with the TCP/IP Socket Server of the PLC (D):
* SAP EWM communicates with PLCs through the Material Flow System (MFS) using an RFC (Remote Function Call) adapter.
* The RFC adapter connects to the TCP/IP socket server of the PLC to transmit and receive data directly.
Incorrect Options:
* B: Sending IDocs via a Post Processing Framework (PPF) is not a standard communication method for PLC integration in MFS.
* C: Direct integration using ABAP Push Channels is not applicable for MFS scenarios.
