We can achieve this with using aggregate stage with ID, Name, LOC as Keys/Group and creating a new column for Count.

First sort the incoming rows by ID, NAME and LOC.
Then take three stage variables in the transformer

StageVar=inputcol
StageVar1=Stagevar
StageVar2=if StageVar=StageVar1 then StageVar2+1 else 1
map the StageVar2 to the output link column
