Order Management integrates with Oracle Inventory Management in the following areas:
Order Management calls Inventory’s reservation APIs to manage reservations. You can create reservations to on-hand quantities from the Sales Orders form. You can also go to Inventory reservation form the Sales Orders form and create a reservation to any level of inventory
(Sub-inventory, locator, lot).When supply is created for an ATO configuration (for a configuration item); it is reserved to a Work Order. This reservation gets transferred to on-hand
When the work order is completed, thus reserves the Order line to on-hand. For every Order created, Order Management creates a record in MTL_SALES_ORDERS, an entity that Inventory uses to manage demand from various sources. Reservation information is stored in MTL_RESERVATIONS. Reservation records for order Lines point to both MTL_SALES_ORDERS and OE_ORDER_LINES_ALL.
Customer-Item Cross reference
You can use Oracle Inventory to set-up Customer Items and Customer Item Cross reference information. You can then place orders using those pre-defined customer item identifiers. Order Management calls the Inventory API INV_CUSTOMER_ITEM_GRP to derive the internal item based on the specified customer item, ship-to site and the warehouse on the Order Line.
The Item Identifier Type on the Order Line indicates the Cross-reference Type that was used for placing the order. The Ordered Item tracks identifier that was used to place the order.
