Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DBD/PSB/ACB Reversal, Catalog Manager or LIU under IMS
  Administration tool decodes incorrect DBD source when the
  utilities process DBD which includes more than 2 FIELDs of
  DFSFIELD, XDFLD and LCHILD in the same segment.

  This APAR fixes the DBDGEN problem with the DBD source decoded
  by the LIU decode function of the DBD/PSB/ACB Reversal, the
  Catalog Manager and LIU under IMS Administration Tool.
  
  When original DBD source, which is used to DBDGEN and the
  generated DBD is the input for the LIU decode function, has
  XDFLD and DFSCASE statement in one segment and DFSCASE has
  more than two FIELDS or FIELD statement is specified after
  DFSCASE statement, the LIU decode function missed to decode
  XDFLD statement with the generated DBD.
  
  PE APAR PH43839 modified the LIU decode function to change order
  of XDFLD and LCHILD statement before DFSCASE statement to use
  the decoded source for the compare function.
  To change the order of field statements, the utility
  internally skipped several internal field blocks. The utility
  misunderstood the field block of FIELD which is related to
  DFSCASE or FIELD after DFSCASE statement as XDFLD related
  field block. As a result of this, the utility missed to
  decode XDFLD statement.
  
  This APAR fixes the LIU decode function of the DBD/PSB/ACB
  Reversal, the Catalog Manager, LIU under IMS Administration
  Tool not to change the order of XDFLD, LCHILD statement and
  DFSCASE statement.
  
  This APAR also fixes the LIU compare function for IMS
  directory and IMS catalog database under IMS Administration
  tool to use correct internal field block when the utility
  need to change the order of XDFLD, LCHILD and DFSCASE
  statement to compare.
