Request to Merge Two Plants into One ERP Warehouse in SAP S/4HANA Public Cloud

[mdd]

The customer requested assistance to merge two plants into one ERP warehouse in SAP S/4HANA Cloud Public Edition.  

The current setup includes two separate warehouses, each with its own plant, storage location, and ERP warehouse number.  

The customer seeks clarification on the feasibility and impact of this structural change and whether it is possible to edit the mapping of plants/storage locations/ERP warehouses. 

They also inquired about the differences between the following scenarios:  
  1. Two plants → two ERP warehouses → one WM warehouse.  
  2. Two plants → one ERP warehouse → one WM warehouse.

As described in the setup guide, the recommended approach is a 1:1 mapping between ERP and WM warehouse numbers. This keeps master data aligned and simplifies integrations, processes, and reporting.

Dear Mr. Horlacher,

Many thanks for your efforts and your response. I understand the recommended approach of maintaining a 1:1 mapping between ERP and WM warehouse numbers.

If we still want to consolidate the warehouses, what would be the best solution in your opinion?

From my perspective, one possible approach could be to create a new storage location and map it to the correct ERP warehouse number. The mapping 2010/2000/200 also one EWM Warehouse must be retired in this case. 

Current Mapping:

Plant Storage Location ERP Warehouse

1010	1000	100
2010	2000	200

Proposed Addition:

Plant Storage Location ERP Warehouse

1010	1000	100
2010	2000	200
2010	2010	100

Would this be a valid and sustainable solution from your perspective, or would you recommend a different approach to achieve warehouse consolidation?
Brgds,

MDD
