| To generate planned orders (RRP run) |  |
| During an order simulation (RRP run), Enterprise Planning generates planned orders to cover inventory shortages. Enterprise Planning uses the following procedure: Determine the finish date. Determine the quantity. Select a source of supply. Select one or more suppliers, and determine the order quantity. Correct the finish date. Determine the start date. Step 1: Determine the finish date For more information, see To compute supply lead-times. Step 2: Determine the quantity ERP LN determines the quantity to be ordered, including all demand within the order interval, and taking the lot-size rules into account. Step 3: Select a source of supply Enterprise Planning can generate three types of planned orders: Planned production order Planned purchase order Planned distribution order ERP LN chooses between these types of orders according to a sourcing strategy. If no sourcing strategy exists, Enterprise Planning uses the default source defined in the Items - Planning (cprpd1100m000) session. Step 4: Select one or more suppliers, and determine the order quantity This step only applies to planned purchase orders and planned distribution orders. If the selected source is purchase, Enterprise Planning searches for one or more external suppliers. If the selected source is distribution, Enterprise Planning searches for one or more internal suppliers. The way the required volume is distributed over various suppliers is determined by the supply strategy defined in the Supply Strategy (cprpd7120m000) session. If no supply strategy is found, Enterprise Planning uses a default strategy. If necessary, ERP LN adjusts the order quantity for planned orders to account for the lot sizing rules. See Lot sizing. Step 5: Correct finish date For more information, see To compute supply lead-times. Step 6: Determine start date For more information, see To compute supply lead-times. Exploded requirements If ERP LN generates a planned production order, it also generates the requirements for the components of the manufactured item. ERP LN takes these exploded requirements into account when it simulates items with higher phase numbers. In case of a multisite simulation, ERP LN also carries out this explosion process for planned distribution orders.
