Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• GU call with 2 SSAs places the root segment data in the I/O area
  erroneously before placing the dependent segment data.  When the
  root segment is longer than the I/O area, the following area is
  overlaid.  This problem occurs when the root segment is
  compressed.

  ****************************************************************
  This APAR fixes the following problems of HP Unload API:
  
  1) GU call with 2 SSAs places the root segment in the I/O area
  erroneously before placing the 2nd level dependent segment data.
  When the root segment is longer than the I/O area, the following
  storage area is overlaid.
  This problem occurs when the root segment is compressed.
  The same situation will occur in the 1st GN call with 2 SSAs.
  
  2) A GU call with 2 SSAs is counted as a GN call erroneously
  in the DB CALL STATISTICS report.
  

Problem conclusion

• The module FABHGSA and FABH002 have been modified as to
  process GU call with 2 SSAs correctly.
