Some Workbench Grids Do Not Show Past Due Data
The Schedule Grid, Supply/Demand Grid, and Capacity Grid do not show data related to past due orders.
Probable Cause
The Schedule Grid, Capacity Grid, and Supply/Demand Grid only show data related to past due orders when they are within the setting of the History Horizon field in the Search window of the Preferences option.
Solution
If you see past due orders but not the detail related to them, expand the history horizon value to see the related data (supply, demand, and so on).
Also, the Production Order Maintenance window within the workbench shows past due orders. Past due open production orders display first, regardless of the history horizon setting you have selected in your user preferences.
