Reservation Processing

Before the order can be released for picking in a WMS, the demand line must set to the releasable fulfillment state by reservation processing in PeopleSoft Inventory. A demand line can be set to the releasable state with soft-reserve, ATP promise, pre-allocation, or just released downstream for picking. A demand line could be fully or partially back-ordered by the reservation process.

Pre-allocations

Pre-allocations are a hard allocation of quantity at the material storage location level when orders are in the unfulfilled state. Pre-allocations include hard allocations created by the pegging feature and lot-allocations. In PeopleSoft Inventory, the Order Release Request process is run to generate the Shipping Order Release EIP. This service operation sends the hard allocations to the WMS . If PeopleSoft Inventory receives a transfer transaction for a pre-allocated item from the WMS, the transaction is rejected because allocated material cannot be transferred. Do not use pre-allocation processing if the WMS implementation has procedures that require transferring material from a material storage location to a shipping area before sending data using the Inventory Pick Confirm EIP or the Inventory Shipping EIP.

Back Orders

If back orders are permitted for orders, the back order processing takes place in PeopleSoft Inventory. Back order functionality in the WMS is not used in a WMS integration. If you allow order lines to ship with partial quantities, demand lines with the available portion of the requested quantity are inserted into IN_DEMAND, where they can be released for picking in the WMS.
