Katherine,
Did you run into the issue on table T5U0C where you need to enter more than one code that has the same last four digits but the major group (first two digits) are different?
Example:
11-1011 Chief Executives
51-1011 First-Line Supervisors of Production and Operating Workers
The SAP key is based on the Occupational Classification Code and not the combination of OCC Code and Group. I am receiving a message stating "an entry already exists with the same key".
Any thoughts before I create an incident?
