how your rank will look like

let suppose
ename sal
a 1000
b 1000
c 2000
d 1000
e 2000
and rank will work upon sal column.

what will be your target as per informatica rank works

ename sal rank
a 1000 1
b 1000 1
d 1000 1
c 2000 4
d 2000 5

if your rank will like this

ename sal rank
a 1000 1
b 1000 2
d 1000 3
c 2000 4
d 2000 5
or

ename sal rank
a 1000 1
b 1000 1
d 1000 1
c 2000 2
d 2000 2

all are can be done by using expression
transformation,sorter and aggrerator transformation combined
in a mapping.

Answer / bhupal

Use sorter t/r first and sort the data by using which port
u want

next use that expression t/r to generate the sequence by
using variable port

next u can use the filter t/r to restrict the data or
required ranks as a output.
