You can create a dynamic port from the All Ports group of a Read transformation, a group of an upstream transformation, or a dynamic port in an upstream transformation. The Developer tool creates dynamic ports with the data type value as dynamic. You can create more than one dynamic port in a transformation.

When you use the

New

button to create a port, the Developer tool assigns a default name. Rename the dynamic ports to ensure that the port names within each transformation are unique. When you add ports of the same name to a transformation, the Developer tool appends a number to the dynamic port or the generated port to resolve port naming conflicts.

You can create dynamic ports in the following transformations:

If the mapping contains transformations that cannot include dynamic ports, you might need to manually update the mapping when the source metadata changes.
