Interface Between EWM and Non-SAP Systems 

Use

Extended Warehouse Management (EWM) has an interface (EWM-WCU interface) that you can use to connect automated warehouse systems such as warehouse control units (WCU) to EWM.

Integration

The interface allows communication between the connected systems on the basis of the transactional Remote Function Call (tRFC).

In contrast to synchronous Remote Function Call (RFC), the system saves the data in an intermediate storage area, before sending it to the connected system. This leads to the decoupling of application and communication.

Features

Interface Between EWM and Non-SAP Systems (WMS-WCU Interface)

You use the EWM-WCU interface to connect automated warehouse systems, such as warehouse control units (WCU) to Extended Warehouse Management (EWM).
