Two ECC systems and a decentralised EWM ( 1909 )

[former_member647058]

Hi Gurus,

I am looking for some best practices/guidance when we have two ECC systems ( one of them is from newly acquired company) and a decentralised EWM ( 1909 ). Kindly let me know if you can refer me to some SAP documentation or guidance from your own experience. My main area of concern in Master Data Management and Partner management.

Hi

"For my understanding, this means that we can connect to two Plants/sloc combination ( from two different Companies -having non-harmonized products) can be mapped to two different EWM 1909 warehouses. This is like two different implementations in same S4 EWM box."

I hope your understanding is NOT that you always connect two plants/sloc combinations to one warehouse. One warehouse means this is ONE physical complex. And would in your scenario your two plants really share one physical warehouse?

"But not possible to connect to one EWM warehouse as per current offering by SAP. Kindly let me know if my understanding is correct. Or even the first option is not possible."

This is not really the problem of the warehouse (number). The problem is on the system side "Connect the EWM client to multiple SAP ERP or SAP S/4HANA systems with harmonized master data". Client means that in one client the system can not really distinguish non-harmonized master data.

So I am afraid your understanding is not correct (at least how I understand the documentation). For the moment you need two separate EWM systems / clients if you have the EWM system on 1909 and two non-harmonized ERP systems. Which is maybe inconvenient, but really only a real problem if the two plants share the same physical warehouse.

Thanks Juergen for your response.

To clarify my understanding, if two plants/sloc are residing in same ECC system/client then we can map them to single Decentralised EWM 1909 system/client. We may use single warehosue no ( for two plants ) or two warehosue nos ( one for each plant) in this scenario.

The main challenge is when the plants are using two separate ECC system/clients. In my case, two plants are using two different ECC system/clients( since this is an acquisition scenario - both plants having its own legacy ECC) and now they want to share a single physical warehouse ( to reduce cost ) which will be configured in a single Decentralised EWM 1909 system/client. ECC systems dont have harmonised master data.

So in this case we cannot go ahead with single EWM system/client as per current SAP offerings. Is this a fair statement ?

Can you please explain ( or refer material to study ) the below sentence.

"Client means that in one client the system can not really distinguish non-harmonized master data."

I am not very clear about what actually are the differences between harmonized and non-harmonized master data. My assumption is that harmonized means both the plants are using same product master. Can you please explain.

Thanks in advance,

Sayan
