Click Layout > Autolink.
Select the transformations and targets.
You can select multiple transformations in the To Transformations list to link one transformation to multiple transformations. For objects that contain multiple input groups such as Custom transformations or XML targets, select the group name from the To Transformation list.
You can also select the transformations in the workspace in the order you want to link them. Then, in the Autolink dialog box, select each From Transformation and the Designer selects the To Transformation based on the order in which you selected it in the workspace. Click Apply and then select the next From Transformation and click Apply.
Select Position.
Click OK.
The Designer links the first output port to the first input port, the second output port to the second input port, and so forth.
