I could not locate the port for non-matched master data records in ExtMergeJoin and ExtHashJoin. Please help. Thank you.

Chapt 39 States - ApproximativeJoin, ExtHashJoin, and ExtMergeJoin have output ports also for nonmatched master data
records. ApproximativeJoin have output ports for nonmatched both master and slave data records.

  Hello,
  
  This is my mistake.
  
  ApproximativeJoin has output port 2 for non-matched master records, output port 3 for non-matched slave records. Ports 0 and 1 for transformed records.
  DBJoin and LookupJoin have output port 1 for non-matched master records. Port 0 is for transformed records.
  ExtHashJoin and ExtMergeJoin have only a single port (port 0) for transformed records.
  
  I created a feature request for non-matched master port for ExtHashJoin and ExtMergeJoin.
