Answer / ram
there are two ways you can get.
1. sort the data in descending order and make true the
create key change column.
2. this can be done in transformer stage at stage variables.
a. first sort the data on descending order (key would the
column which you wanted to be).
define three stage variables in transformer....sv1,sv2 & sv3
set sv2 and sv3 initial values to 0.
if (salary=sv3) then sv2 else (sv2+1) ------> sv1
sv1 -------> sv2
salary --------> sv3
in next link filter...
now you can see all 1st highest salary, 2nd highest
salary..and so on
