| # ATP Time-phased calculation If you only want to check ATP for a plan item, without performing component CTP, capacity CTP, and channel ATP, the calculation is based on the order plan of the item. As a result, the detailed transactions of the plan item are used to see exactly when ATP is created. Therefore, this calculation is not a bucket-based calculation, but a time-phased calculation. The user receives the most detailed answer. Whether the plan item has a master plan or not is irrelevant. In both situations, the previous detailed time-phased calculation is used, in the order horizon as well as in the planning horizon. Therefore, in this case, no difference exists between order-based and master-based checks. To achieve this type of calculation: Start the Items - Planning (cprpd1100m000) session. On the CTP tab, select the Online ATP Update check box. On the CTP tab, clear the Component CTP check box. On the CTP tab, clear the Component CTP check box. On the CTP tab, clear the Channel ATP check box. |
