Ports have attributes, such as datatype and precision. When you create a Custom transformation, you can create user-defined port attributes. User-defined port attributes apply to all ports in a Custom transformation.
For example, you create a external procedure to parse XML data. You can create a port attribute called “XML path” where you can define the position of an element in the XML hierarchy.
Create port attributes and assign default values on the Port Attribute Definitions tab of the Custom transformation. You can define a specific port attribute value for each port on the Ports tab.
When you create a port attribute, define the following properties:
Name.
The name of the port attribute.
Datatype.
The datatype of the port attribute value. You can choose Boolean, Numeric, or String.
Value.
The default value of the port attribute. This property is optional. When you enter a value here, the value applies to all ports in the Custom transformation. You can override the port attribute value for each port on the Ports tab.
You define port attributes for each Custom transformation. You cannot copy a port attribute from one Custom transformation to another.
