Mapping Input Ports to the Method Input

When you show the transformation input mapping, you can define input groups, define input ports, and map input ports to method input elements.

Open a REST Web Service Consumer transformation.

In the

Ports

view, show the input mapping.

Define a primary key for the root input group.

To add an input group or port to the

Ports

area, use one of the following methods:

Method	Description
Drag an element.	Drag a group or a child element from the Method Input area to an empty column in the Ports area. If you drag a group to the Ports area, the Developer tool adds a group without ports.
Manually add a group or port.	To add a group, click the arrow next to the New button, and then click Group . To add a port, click the arrow next to the New button, and then click Field .
Drag a port from another transformation.	In the editor, drag a port from another transformation to the REST Web Service Consumer transformation.
Copy a port.	Select ports from another transformation and copy them to the Ports area. To copy ports, you can use keyboard shortcuts or you can use the Copy and Paste buttons in the Developer tool.
Select Map first level of hierarchy .	The Developer tool maps elements in the first level of the method input to input ports and groups. The Developer tool also creates the input ports and groups to perform the mapping.

If you manually create a port or you copy a port from another transformation, click the

Location

column in the

Method Input

area and choose a port from the list.

To map input ports as a composite key, use one of the following methods:

Method	Description
Drag input ports.	Select two or more input ports, and drag them to a key in the method input hierarchy.
Select input ports from the Select Location dialog box.	Click the Location column of a key in the method input hierarchy and then select the input ports.

To clear the locations of elements, use one of the following methods:

Method	Description
Click Clear .	Select one or more elements in the Method Input area and click Clear .
Delete the lines that connect ports to elements.	Select one or more lines that connect the input ports to the elements in the method input, and press Delete .
