Answer Posted / indu
Input->Sort1->Sort2->Trnsformer->Output
Sort1-->Declare class_id and Marks as key column and sort
in descding order.
Sort2-->Declare class_id and Marks as key column(Sort Mode
to Dont sort previously sorted for both) and set clustered
key change column to true.
Otuput for Sort 2 will be
class_id Marks Rank
102 90 1
102 35 0
101 60 1
101 50 0
101 40 0
In the Transformer declare stage variable temp and
initialize to o
Derive temp--> If Rnak=1 then Rank else temp+1
Derive output columns as --->
class_id ---> class_id
Marks ----> Marks
Rank----> temp
