Problem conclusion

• GEN:
  POSTREQ PI18330
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  DFSYSPO0 was modified to add IFP support for CM1 ACK timeout.
  
  DFSYPSI0 was modified to generate an additional 6701 trace
  record for the DFS1283E/DFS1284E. This new trace entry will
  only be generated if DFS1283E/DFS1284E is issued, regardless if
  TPIPE trace is on or off. For a DFS1283E/DFS1284E condition two
  6701 trace entries will be generated, ID=YACK or ID=YNAK, which
  contains the OTMA message prefix, and ID=1283 or ID=1284, which
  contains the TMEMBER and TPIPE blocks.
