Where Do You Define Issue Codes?

 

Issue codes are defined in the Part Master File Maintenance conversation on the Control screen.  You may, however, change the issue code of the component requirements of manufacturing orders only in the Manufacturing Order Maintenance conversation (IC100), but only if the order is planned or firmed, not open.
