Port Selector Configuration

When you configure a port selector, you define selection rules to determine which generated ports to include. The selection rules are similar to the input rules that you can configure for dynamic ports.

A port selector can include static or generated ports. Configure a port selector on the

Port Selector

tab.

The following image shows the

Port Selector

tab:

Configure the following properties for a port selector:

Name: Identifies the port selector. You can create multiple port selectors in a transformation and reference them in expressions.
Scope: Identifies a group of ports that the port selector applies to. You must choose the scope when you create a port selector for a Joiner or a Lookup transformation. These transformations have multiple input groups. The Joiner transformation has a Master or a Detail scope. The Lookup transformation has an Import or a Lookup scope. The Expression transformation has one input group. The scope is always All Ports.
Selection Rules: Determines the ports to include in the port selector. When you create the selection rules, the
Port Preview
panel shows the ports that qualify from the current input ports. These ports might change. Configure the selection rules to accommodate ports from different sources.
