The key field needs to be in the record format.
The record format that OPNQRYF is building contains only the detail information 
(FORMAT(INVDET))  Since the name isn't in the record, the system can't sequence 
the records by name.  The "common?!" solution is to create a new file that 
contains the fields you want from the detail and header.  Use that file as your 
FORMAT and as your input file in the RPG.
