An Expression transformation has the following generated input ports:

EMPNO   Decimal
NAME    String
SALARY  Decimal
DEPTNO  Decimal

The transformation contains a dynamic output port called MyDynamicPort. The output port returns the results of a dynamic expression. The dynamic expression multiplies the value of each port in a port selector by 100. The expression runs one time for each port in the port selector. Each instance can return a different result. The Expression transformation generates a separate output port for each result.

The Decimal_Selector port selector has a selection rule that includes the ports that are of decimal data type:

EMPNO   Decimal
SALARY  Decimal
DEPTNO  Decimal

The following image shows a dynamic expression that references the Decimal_Selector port selector:

Edit the output port settings to change output port names and output port properties. You can also choose the base port.
