Target.
Connect the source qualifier transfromation to an
expression transformation. In the expression
transformation, create the below ports:
v_cnt (variable port) = v_cnt+1
o_cnt (output_port) = v_cnt
Connect the expression transformation to the sorter
transformation. Sort the rows on the o_cnt port in
descending order.
Now connect the sorter transformation to the expression
transformation (do not connect o_cnt port).
Again Connect to expression transformation create the ports
mentioned above
v_cnt (variable port) = v_cnt+1 o_cnt
(output_port) = v_cnt
Connect to a filter transformation and specify the filter
condition as o_cnt<=N
Connect the expression transformation to the sorter
transformation. Sort the rows on the o_cnt port in
descending order.
Connec to the target
