Scenarios for Connecting Non-SAP Systems 

Use

You can use the interface between Extended Warehouse Management (EWM) and non-SAP systems (EWM-WCU interface) to connect different non-SAP systems to EWM. The following scenarios give you an overview of typical ways in which this interface can be used.

Non-SAP systems include warehouse systems dependent on EWM, such as warehouse control units (WCU).

Features

The EWM-WCU interface supports the following communcation transactions between the systems:

●     Transfer warehouse tasks from EWM to non-SAP system

●     Transfer release of multiple processing from EWM to non-SAP system

●     Transfer cancellation requests from EWM to non-SAP system

●     Create transfer orders in EWM for warehouse tasks reported by non-SAP system

●     Confirm transfer orders in EWM for warehouse tasks reported as complete by non-SAP system

●     Move handling units

●     Blocking storage units or aisles

●     Cancel transfer orders in EWM for warehouse tasks not reported as complete by non-SAP system

EWM takes on all tasks related to warehouse management. However, warehouse control and execution of driving commands are not part of EWM's tasks.

For this reason, the non-SAP systems always represent standalone systems for the SAP system, which can take on control of the product flow, as well as other tasks such as optimizing the stock movenents or additional control mechanisms.

The scenarios focus on the task distribution between EWM and the relevant connected non-SAP system. The flexibility of the EWM-WCU interface enables you to make customer-specific adjustments and enhancements.

Activities

You determine the task distribution, according to your own requirements, between EWM and the non-SAP system.
