Receiving and backflushing increases end-item inventory quantities at designated sites and locations and decreases component inventory. It also updates the work order to reflect quantities completed and scrapped, decreases quantities open for MRP, and adjusts work in process (WIP).

MRP plans for open component requirements. Issuing a required component or an approved substitute decreases the quantity required of that item for planning. It also increases the value of WIP. Issuing a component not listed on the work order also increases WIP.

Recording a receipt or scrap decreases the scheduled receipt quantity for planning. Receipts and scrap can total more than order quantity. Receipts and scrap decrease the value of WIP.

You can change the quantity to issue for any item when Modify Backflush is Yes in the first frame of Flow Schedule Receipts. When you do not need the entire quantity of an item, issue the quantity you need and set Cancel B/O to Yes to cancel the excess requirement for MRP.

The system maintains a complete audit trail of inventory transactions in transaction history (tr_hist). Review these with Transactions Detail Inquiry (3.21.1). Each transaction is identified by a transaction number and a transaction type. Five types of transactions can be created:

When an inventory transaction references a different site than the originating order, the system processes this transaction in two steps.

This generates additional transaction types ISS-TR and RCT-TR.
