Specify a transform, a cast function, or an XPath function between two or more elements by selecting from the list of available mapping operations that are shown on the connection.
Learn about the different mapping operations. For more information, see Transforms (Mapping operations).
In the Graphical Data Mapping editor, you can use transforms, cast functions, and XPath 2.0 functions to run different actions on input data and move the result to the output element. You choose the appropriate mapping operation that is based on the result that you want to achieve.
When you create a connection between two or more elements, a transform is assigned, based on the number and type of input elements. You can then change the transform by choosing from a list of available transforms. If a particular transform type is not shown in the list, that transform is not valid for your input and output elements.
For example:
The following steps show how to change the transform that is selected, and also how to add more elements:
Configure the properties of the transform. For more information, see Configuring the properties of a transform.
