• Create an expression transformation, connect all ports from source qualifier to expression.

• Add other output port to expression with O_ENAME

• O_ENAME=ENAME

• Create aggregator transformation, connect all ports from expression to aggregator.

• In the aggregator, groupby on all columns

• Write a expression on O_ENAME

• O_ENAME=count(ENAME)

• Connect all ports from aggregator target

• connect O_ENAME to COUNT in target
