Organizational Model for Production Supply

There are different models for organizing stocks in the production supply areas (PSAs) in Extended Warehouse Management (EWM).

Separate Storage Bins in the EWM System

The system manages the stocks in the PSA separately from the other stocks. This increases the transparency at storage bin level in the EWM system, and at storage location level in the ERP system. When staging at the PSA, the EWM system executes a posting change by changing the stock type. In the ERP system, this is a stock transfer between the storage locations.

EWM-Managed Storage Location

The PSA stocks are only managed in EWM, and are therefore transparent in the EWM system only. When staging at the PSA, the system does not execute a posting change.

MM-IM Managed Storage Location

The PSA stocks are not managed in the EWM system. They are managed in the ERP system at MM-IM storage location level. Staging at the PSA is an outbound delivery from an EWM perspective, and, from an ERP perspective, a posting change to a storage location outside of the EWM system.

EWM-Managed Storage Location in Another EWM Warehouse

The PSA stocks are managed in the EWM system in another warehouse number. The staging takes place in a two-step posting change:

Of the outbound delivery from the sending EWM warehouse
Of the inbound delivery to the receiving EWM warehouse
