Src>> Sort1 >> Sort2 >> Transfrmr >> Trgt
Sort1 --> sort with class_id and marks as well.
Sort2 --> declare key as id and select Dont Sort(Previously Sorted) and set create cluster key change column as True.
Transfrmr --> set two stage variables.
StageVar1=If Clusterkeychange=1 then Clusterkeychange else StageVar+1
StageVar=StageVar1
Create a new row as rank in transfrmr output and map StageVar1 to rank
