If you optimize an optimized program again, it changes the current feeder assignment. Or even though you try to change the current feeder assignment by the Optimization function, it does not change the feeder assignment.

Cause: The "Pick Data" field is not set correctly on the "Assignments" option tab of the "Optimization" Screen.

Corrective action:
Make setting of the "Pick Data" field on the "Assignments" option tab of the "Optimization" Screen as follows:
If you want to change the current feeder assignment
Select " Auto assign all data"
Otherwise
Select " Use manual position assignment"
