OPNQRYF a flat file?

[D.BALE@xxxxxxxxxxxxx]

Can OPNQRYF be used on a non-externally described flatfile?  The flatfile maps
to a file that is externally described, and will eventually be copied to files
with the externally described format, but first I have to run the flatfile
through OPNQRYF to determine all the unique release numbers found in the file.
 Note that ASNPK is the externally described file and DANBALEZ is the
non-externally described flatfile.  ORRNPK is the Release Number field,
defined as 7-digits, zoned decimal.

> OVRDBF FILE(ASNPK) TOFILE(DANBALEZ) SHARE(*YES)
> OPNQRYF FILE((ASNPK)) KEYFLD((ORRNPK)) UNIQUEKEY(*ALL)
  File ASNPK overridden.
  Field ORRNPK on KEYFLD parameter not found.
  Error occurred during processing of command.

So then I tried:

> ovrdbf danbalez share(*yes)
> OPNQRYF FILE((DANBALEZ)) FORMAT(ASNPK)
     KEYFLD((ORRNPK)) UNIQUEKEY(*ALL)
  Field BRANPK on FORMAT parameter not found.
  Error occurred during processing of command.

BRANPK is the first field defined in the ASNPK record format.  I got the
feeling that I'd have to MAPFLD all 79 fields in the ASNPK file to get this to
work.  Not worth it.

Note: PTCKON08 is the flatfile's record format name & single field name.

> ovrdbf danbalez share(*yes)
> OPNQRYF FILE((DANBALEZ)) KEYFLD((ORRNPK)) UNIQUEKEY(*ALL)
     MAPFLD((ORRNPK '%sst( PTCKON08  524  7 )' *ZONED 7 0))
  Key field *MAPFLD/ORRNPK not valid for record format.
  Error occurred during processing of command.

> ovrdbf danbalez share(*yes)
> OPNQRYF FILE((DANBALEZ)) FORMAT(ASNPK) KEYFLD((ORRNPK))
     UNIQUEKEY(*ALL)
     MAPFLD((ORRNPK '%sst( PTCKON08  524  7 )' *ZONED 7 0))
  Field BRANPK on FORMAT parameter not found.
  Error occurred during processing of command.

> OVRDBF FILE(ASNPK) TOFILE(DANBALEZ) SHARE(*YES)
> OPNQRYF FILE((ASNPK)) KEYFLD((ORRNPK)) UNIQUEKEY(*ALL)
  File ASNPK overridden.
  Field ORRNPK on KEYFLD parameter not found.
  Error occurred during processing of command.

> OVRDBF FILE(ASNPK) TOFILE(DANBALEZ) SHARE(*YES)
> OPNQRYF FILE((ASNPK)) FORMAT(ASNPK) KEYFLD((ORRNPK))
     UNIQUEKEY(*ALL)
  File ASNPK overridden.
  Field BRANPK on FORMAT parameter not found.
  Error occurred during processing of command.

SO I AM ASKING...  CAN THIS BE DONE WITH OPNQRYF?  Or am I stuck with having
to use an RPG solution?
