To update master-plan dataYou can run the Initialize, Roll, and Update Scenario (cprpd4200m000) session (with the Generate Item/Channel Master Plan check box selected) to update item master plans and, if applicable, channel master plans for a range of plan items. This topic describes the various steps of the procedure involved. Note A similar procedure is carried out when you choose Generate in the Item Master Plan (cprmp2101m000) session. In this procedure, no supply plan is generated. If you want to generate or update supply plans, run the Generate Master Planning (cprmp1202m000) session or the Generate Master Planning (Item) (cprmp1203m000) session. If necessary, LN first rolls the scenario. See To use a rolling scenario. Next, LN (re)generates the master plans of the selected plan items. The plan items are processed in order of phase number. Note When a scenario is rolled forward, LN updates the planning data for all plan items. Procedure The update procedure consists of the following steps: Step 1. Retrieve goods flow data from Warehousing If you select the Update Goods Flow Data check box in the Initialize, Roll, and Update Scenario (cprpd4200m000) session, LN retrieves the goods flow data from the execution level. For channel master plans, only customer order data is retrieved. See To update goods-flow data. When you choose Update in the Item Master Plan (cprmp2101m000) session, this step is always carried out. If the plan item is a product family, Enterprise Planning does not retrieve the goods flow data from the execution level. Instead, Enterprise Planning aggregates this data from the item master plan of the child items to the item master plan of the family, based on the aggregation relationships. Note
Step 2. Update receipts and requirements from Enterprise Planning LN updates the following fields in the Item Master Plan (cprmp2101m000) session:
Note
Step 3. Consume demand forecast LN uses the actual demand to consume the demand forecast, the extra demand, and the special demand in the same or nearby plan periods. Step 4. Generate critical requirements If you select the Generate Requirements check box in the Initialize, Roll, and Update Scenario (cprpd4200m000) session, LN generates the material and capacity requirements based on the following: Note
Step 5. Recompute projected inventory and ATP LN updates the following fields in the Item Master Plan (cprmp2101m000) session:
For channel master plans, the channel ATP is recomputed. If you select the Multisite Updating check box in the Initialize, Roll, and Update Scenario (cprpd4200m000) session, LN carries out the steps listed above for each logistic plan within the multisite structure. See Multisite planning. After the update, LN updates all resource master plans that need to be updated. You can view the results of the update in the following sessions:
