  1. DEDB hash check issued FABA4031E (SDEP pointer error) message
     when a deleted SDEP segment detected between SDEP LB and LE.
  
  2. The succeeding steps report the same error as the
     previous step.
  

Problem conclusion

• FABAHEXT and FPBAHSCA have been modified to consider the deleted
  SDEP segments between SDEP LB and LE in HASH checking,
  and issue FABA4057I when the first deleted SDEP segment is
  detected.
  
  FABAHEXT and FABAHPC0 have been modified to reset
  the processing flag at the beginning of per area processing.
  
  FABAHDAT has been modified to add FABA4057I message ID.
  FABAMSGS has been modified to add FABA4057I message text.
