Answer / sujatha
in the sq data has to be order by key column..then in the
expression trans we have to create a variable port to hold
the previous records key value...and one more variable port
to compare with the current records key value...if the prev
and curr are equal then the 2nd variable value will
get 'Y',if not equal its value will be 'N'.
Take a router ,process the rows which are having the 2nd
variable value as 'N' to the target....these are unique recs
