Net Change in Demand
Net change in demand is a number that represents the net change in component demand due to a quantity change on the parent item. Net change in demand can be negative or positive.
The system calculates net change in demand for only the first-level components of a parent item. The system stores the net change in demand value in the Item Summary Work Table (F34X101W).
For new planned orders, the net change in demand is the total of the pegging record quantities in the primary UOM.
For existing planned orders, the net change in demand is the total of unsaved changes in quantity in the primary UOM.
For work orders without a parts list, the net change in demand is the total of unsaved changes in quantity in the primary UOM.
For work orders with a parts list, the net change in demand is the total of unsaved changes in quantity in the primary UOM.
When you select the Refresh S/D option on the Row menu of the Planning Console program, the system resets the net change in demand to zero for the parent item and all critical components in the Supply/Demand Details group.
Net change in demand data remains at all levels as you navigate between the parent item and component items. If you exit the Planning Console program without saving the data, or click the Refresh button, the system resets the net change in demand.
When you click the Save Plan button on the Planning Console form, the system saves changes to the plan only for the item/branch displayed on the Planning Console form.
The system decreases net change in demand by the total of quantity changes for the first-level components of the item that you save.
When a component is defined as critical on multiple subassemblies, a balance of net change in demand remains until you save all corresponding parents.
The system saves and implements changes to the plan only for the item/branch displayed on the Planning Console when you click the Implement Plan button.
The system refreshes the supply and demand information so that the system clears all net change in demand.
