A works order is late according to the material dependencies window. However in the Gantt Chart this WO task is not highlighted as late, neither with the red flag (which is normally shown), neither with the Colour by feature.
It's important the Gantt chart labels and colour feature work as expected otherwise we cannot rely on the system to plan tasks.
The functionality has been enhanced in Orchestrate version 7.82. Please upgrade to this version or above.
