Multiple storage locations in EWM / GR- and GI-Zones

Dear all,
we want to install an EWM Warehouse with multiple storage locations of one common plant.
Separation of stocks by use of availability groups, that are assigned to storage types, is finished so far.
For each storage location i have created a set of stock types (e.g. 1F, 1B, 1Q, ... 2F, 2B, 2Q and so on).

We receive goods in different storage locations and also deliver from different storage locations, so we have different physical GR-/GI-Zones. We also consume raw materials from two different storage locations
What is not yet clear for me is, how to handle the GR- and GI-Zones and the production supply areas (storage type 1000).
Do i need an own storage type for GR/GI/Production (and perhaps also own inbound-/outbound processes) for each involved storage location?

    Hi Peter,

    1 IM storage location = 1 EWM availability group.

    1 storage type can be hard-linked to one availability group if you check the field "Mandatory" in customizing of the storage type. In this case, you need (at least) one storage type per IM storage location:

    1 IM storage location = 1 EWM availability group = n EWM storage types.

    But if you don't check the field "Mandatory", you can have stock belonging to different IM storage locations in the same storage type (even in the same bin):

    n IM storage locations = n EWM availability groups = 1 EWM storage type.

    I don't know your requirements, but most scenarios I know work like this:

    • GR area is "neutral" (field "Mandatory" not checked). When you receive goods, they will belong to the storage location / availability group that is in the original document (inbound delivery or expected goods receipt).
    • Final warehouse is hard-linked to an availability group / storage location (field "Mandatory" checked). This way, when the putaway is completed, the goods are moved to a different storage location automatically.
    • GI and PSA are "Neutral" in SAP example warehouse 0001, but I usually set them up as "Mandatory" if the customer requests to have visibility of already staged goods in ERP. Then, during picking, goods are automatically posted to a third storage location.

    So it completely depends on your requirements. Think that a warehouse can perfectly work with a single storage location if there is no business reason to have more than one.
