PI22476: DATA TRANSFORMATION INCORRECTLY PARSING ADF WHEN A RECORD IS REUSED WITHIN A NESTED LOOP. EDI OUTPUT IS MISSING SEGMENTS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Environment: WDI MP V3.3.0 on Windows with SFP9
  
  ADF to EDI data transformation incorrectly parses ADF input
  when a record is reused in a nested loop and the record is the
  first record of 2 different loops.  The ADF uses the same
  NAD record definition under both the NAD_LOOP (under base)
  and nested NAD_LOOP_CUS (under EQD_LOOP).
  
  The output EDI is correct when the input contains a repeating
  parent NAD_LOOP with no children, e.g. ...NAD, NAD, NAD, NAD...
  
  However, the EDI output is incorrect when the NAD_LOOP contains
  child records, e.g.
  NAD, LOC, CTA, CTA, CTA, CTA, COM, COM, DOC, DTM, TCC, PRI...
  NAD, NAD, NAD
  In this case, the last 3 NAD loop iterations (2nd through 4th)
  are missing from the EDI output.
  
  An additional symptom resolved by this APAR is that the
  following error is thrown when parsing ADF input that does
  not match the hierarchy as defined in the Data Format.
  
  Message: UP0021 Severity: 08
  Unable to identify the input data record.  Record number was n.
  Data Image <record data from input>.
  **** File: //'EDI.TE52INT.CPP(EDIUPADF)' Line: 1472 Func:
  RawDataParse(Ctxt *)
  
  Prior to this fix, the ADF parser would lose position within
  hierarchy and EDI output would be dropped or missing. With
  this fix, the UP0021 error is correctly issued thereby
  identifying the record number (n) at which a child loop is
  found without its associated parent.
  

Local fix

• If possible, and as in the problematic scenario noted, reorder
  the input as follows:
  NAD, NAD, NAD
  NAD, LOC, CTA, CTA, CTA, CTA, COM, COM, DOC, DTM, TCC, PRI...
  

Problem summary

• DATA TRANSFORMATION INCORRECTLY PARSING ADF WHEN A RECORD IS
  REUSED WITHIN A NESTED LOOP. EDI OUTPUT IS MISSING SEGMENTS.
  

Problem conclusion

• Issue affects all environments.  Problem caused
  with reuse of records in 2 different loops.  The ADF
  parser is moving out of the current domain and matches
  the second NAD with the EQD domain.  The parser code
  will be modified to check the domain when matching the
  record and move out through the domain stack to continue
  searching for a match on the record.
