Steps to Propagate Port Attributes

Complete the following steps to propagate port attributes:

Open a mapping in the Mapping Designer, and select one or more ports to propagate.

Click Mappings > Propagate Attributes, and choose Propagate Attributes. Or, right-click the port and choose Propagate Attributes.

The Designer displays the Propagate Port Attributes dialog box.

After you open the Propagate Port Attributes dialog box, you can select another port and propagate its attributes.

Select the direction and attributes you want to propagate.

Optionally, to infer dependencies, click Options.

The following table describes the options on the Propagate Port Attributes dialog box:

Option	Description
Preview	Displays the links to the affected ports in green and the unaffected ports in red.
Propagate	Propagates the port attributes according to the options you specify in the dialog box.
Direction	Instructs the Designer to propagate attributes forward, backward, or in both directions.
Attributes to Propagate	Specifies the attributes that you want to propagate. The attributes include name, datatype, precision, scale, and description.
Options	Select to read conditions or expressions and propagate attributes to implicit dependencies. The Designer disables these options when you propagate the port name. These options are clear by default. When you select one of these options and click Preview, the Designer highlights the link paths to the dependent ports.

Click Preview to view the affected ports.

The Designer displays the links to the affected ports in green and the unaffected ports in red.

Click Propagate.

When you propagate port attributes, the Output window displays the propagated attributes and the affected ports.
