When you create a Macro transformation and assign a macro instruction mapplet to the transformation, dynamic input and output ports are created based on the input and output groups of the macro instruction.

By default the output ports have the same type, precision, scale, and description as the input ports. You can configure the output ports by editing the base port associated with each output port in the

Ports

properties.

The number of generated ports created by a dynamic port in the Macro transformation must be either one or equal to the number of ports generated by the other dynamic ports in the transformation, excluding the passthrough ports. The passthrough ports in the Macro transformation can have any number of generated ports.

For example, a Macro transformation has three dynamic ports

transformed_input1

,

transformed_input2

, and

passthrough_input

. If

transformed_input1

generates three ports, then

transformed_input2

must generate either one or three ports.

passthrough_input

can generate any number of ports.
