By using the stage variables in transformer we can do this.
Before going to use transformer sort the data based on two columns.Order should be like below
Deptno Empname
10 A
10 B
SO ON...
After that in transformer take 3 stage varibles
stg1--->map the sorted Deptcolumn
stg2---> DSLink2.empname:',' (map the empname column and concatenate comma operator)
Stg2--->stg3:stg2 (concatenate first two staging varibles)
Then
In derivation of employee_list column (In transformer)
use below function
TRIM(stg3,',','T')---->employee_list (column derviarion)
It will gives you as expected result.
Thanks
