SAP EWM MFS VS WCU Interface

Hi Experts

I have client who is already having automated warehouses with 3 different non SAP MFS. They are in plans for implementing SAP EWM. I have to propose solution for MFS. In this process debating on implementing SAP EWM MFS Or use SAP EWM WCU interface.

Here is my basic understanding. Please suggest from your experience. Correct my understanding, in case wrong.

SAP EWM MFS means warehouse management & warehouse control done by EWM. This will provide accurate status of HU i.e current communication channel and communication point in process. Telegram messages are integrated into monitor for better trouble shooting. However implementation will take more time considering number of automated WH & different type of equipment i.e Std. conveyor, A frame conveyors, work station of id points etc). Testing solution also complicated and time consuming.

On the other hand SAP EWM with WCU interface...EWM only does warehouse management & lets 3rd party MFS handle warehouse control. This way current setup is not disturbed. We will be using mostly std. SAP IDOC types of WCU interface. So implementation is also not complex. However monitoring and control is not well integrated. Is there a way to know exact location of HU in the process? Or EWM is in blind till WT confirmation IDOC received from MFS?

Please let me know any other disadvantages of using WCU interface VS EWM MFS. Thank you.

Best Regards

Plant Connectivity in built-in part in EWM MFS. So, you doen't requrie external Plant Connectivity.

For Non Production Environment testing, you have simulators. These software will be given by your hardware(AS/RS) suppliers. your warehouse team must be having these simulators.
