| To use planned delivery moments |  |
| In purchase scheduling, planned delivery moments must be generated for a combination of item, buy-from business partner, ship-from business partner, and warehouse, which are used by Enterprise Planning for lead-time offsetting. To generate planned delivery moments, refer to Overview of purchase schedule handling. When Enterprise Planning calls the Purchase Control module for planned delivery moments for a combination of item, buy-from business partner/ship-from business partner, and warehouse, ERP LN carries out the following steps: Searches the Delivery Patterns by Warehouse / BP / Item (tdipu0124m000) session to retrieve the applicable delivery pattern. ERP LN searches in the following order: By warehouse, buy-from business partner, ship-from business partner and item. By warehouse, buy-from business partner, and ship-from business partner. By warehouse. Determines whether the purchase schedule is delivery-based or shipment-based. If a purchase schedule already exists for a combination of item, buy-from business partner, ship-from business partner, purchase office and ship-to address, ERP LN checks whether the schedule is shipment-based or delivery-based from the Shipment/Delivery Based field in the Purchase Schedules (tdpur3110m000) session. If a purchase schedule does not exist, a new schedule is generated. In this case, the delivery-based or shipment-based information is retrieved from the Purchase Contract Line Logistic Data (tdpur3102m000) session or the Items - Purchase Business Partner (tdipu0110m000) session. If the schedule turns out to be shipment-based, Enterprise Planning reads the planned delivery moments for a combination of warehouse, ship-from business partner and delivery pattern from the Planned Delivery Moments (Shipment Based) (tdipu0125m000) session. If the schedule turns out to be delivery-based, Enterprise Planning reads the planned delivery moments for a combination of warehouse and delivery pattern from the Planned Delivery Moments (Delivery Based) (tdipu0126m000) session.
