MSW displays visual status indicators to direct your attention to potential capacity and item shortage issues. The projected quantity on hand (POH) displays as soon as items display on the Schedule Grid. The system calculates the POH for every item with supply/demand in the scheduling horizon. When the resource type is a production line, the system applies the indicator to only the item’s primary production line. When the resource type is a work center/machine, the system applies the indicator to any resource associated with the item.

Shortage warning status applies to required capacity, available capacity, part number, scheduled quantity, and projected on-hand (POH) quantity. Shortage warning status indicators can display as a low warning status (yellow shading), which typically applies to non-critical potential shortages; for example, when the quantity on hand does not meet safety stock requirements. A high warning status (red shading) indicates a potentially critical capacity or item shortage problem; for example, when the projected on hand quantity is less than zero. Chapter 1 summarizes visual indicators.
