If no Coil number is entered in the Load Coil screen a new coil is not loaded, even if the OK button is selected. Subsequent code that prompts for Thread-Up scrap was unaware of this and attempted to use the coil to report production. On the PC Simulation this causes an application crash. It is not known what occurs on the hardware.

To prevent this issue, the Load Coil Screen will not respond to the OK button until a Coil Number has been entered.
