Available to promise for clustered items

You must set up a plan item’s available-to-promise functionality in the Items - Planning (cprpd1100m000) session, on the CTP tab.

For clustered items, the use of component and capacity CTP is restricted. Only one of the clustered plan items and nonclustered plan items can be supplied by means of the source production. If multiple clusters have the source production, the capable-to-promise functionality produces erroneous results, because the system promises the same capacity and components to multiple orders: once for each cluster. This happens because a clustered item cannot have a unique bill of material, bill of critical material, routing operations, or bill of critical operations.

If Enterprise Planning reserves and checks capacity CTP on a clustered item, the same capacity can be promised to multiple orders: once for the clustered item, and once for the nonclustered item.

No functionality for disaggregating distribution orders to a clustered item is available. Therefore, LN does not calculate the channel ATP automatically, if the clustered item has the source Distribution. For these clustered items, you must manually enter a quantity in the Allowed Demand field to maintain the channel ATP in the channel master plan.
