Answer / kalyan
Do a lookup on the Target table with an Lookup SQl Override
Select MAX(FIELD_NAME), field 1 , field3 from target group
by field1, field2...
In the Expression increment the Max values of the field

Here MAX_FIELDNAME) is the Max value of the field you want
to generate the sequence of..

TAKE EXPRESSION TRANSFORMATION AND DOUBLE CLICK ON THE
EXPRESSION TRANSFORMATION AND ADD TWO NEW PORTS
1.SEQ
2.SEQ_OUT
1.IN THE SEQ PORT CHECK V=VARIABLEPORT THERE YOU MENTION
EXPRESSION SEQ+1.
2.IN THE SEQ_OUT PORT CHECK O=OUTPUTPORT THERE YOU MENTION
EXPRESSION IIF(ISNULL(SEQ),O,SEQ)
IT WILL GIVE CORRECT RESULT

create two ports

Answer / arnab
either use oracle to generate the sequence number or use an
unconnected lkp transformation which looks up on the
target, get the max(value) of the column which has to be
incremented and increment the value by 1
