From Item/Setup Group

Select the item or setup group that the resource is initially set up for in this changeover relationship.

Note:  You can enter &LTDEFAULT> (with the &LT and > symbols) in the From and/or To fields to represent situations where the Scheduler encounters a From-To combination for which there is no specific setup matrix record.
Note:  If the Show in Drop-Down Lists check box on the Items form is cleared for an item, it will not display in this field. However, you may manually enter the item without causing an error.
