The resulting one-to-one mapping is the same as a one-to-one mapping that you create by creating a connection between a source element and a target element (see Creating a one-to-one mapping).
To create a one-to-one mapping using these two steps:
First, create a new transform with a source element connected to it:
Select a source element (see Source elements, target elements).
On the toolbar of the mapping routine area, click Create
a New Transform
.
The mapping editor creates a new transform, sets it to the appropriate default transform type, and connects the selected source element to the new transform (see Default transform type).
In the mapping routine area, right-click a source element.
The mapping editor creates the new transform in the same way that
it does when you click the Create a New Transform
icon on the mapping routine toolbar.
