Four-Wall Warehousing Functions in a WMS Integration

This section discusses:

• Inventory adjustments.

• Storage location transfers (inventory status updates).

• Physical inventory (stock quantity snapshots).

Four-wall functions are material management activities bounded by the four walls of a specific warehouse, including performing cycle counts and full physical inventory counts, adjusting quantities for specific material storage locations, replenishing fixed picking locations, and making any other stock transfers between material storage locations. In a WMS integration, all four-wall functions are performed in the WMS and then reported to the PeopleSoft system by using EIPs.

Process Flow for Four-Wall Warehousing Functions in a WMS Integration

The following diagram shows the process flow for four-wall EIPs in a WMS integration. The WMS performs any wall-to-wall inventory counts or cycle counts and then passes the data to PeopleSoft Inventory using the Physical Inventory service operation. The WMS also performs any warehouse transfers or stock adjustments and passes this information to PeopleSoft using the Inventory Transfer service operation and the Physical Inventory service operation:

The following diagram shows the process flow for four-wall EIPs in a WMS integration.

The EIPs that support the four-wall functions in a WMS integration are based on a number of assumptions. The following sections detail the assumptions for each function.
