When you open the implementation diagram of a mapping operation, a new tab opens, and the mapping diagram is displayed in the mapping editor.
This is where you model your data mapping.

Customizing the Mapping Editor

When starting with a new mapping diagram, the mapping editor displays a canvas that contains the incoming and outgoing parameters of the mapping operation. The image above shows the blank mapping diagram of a non-static mapping operation.

On the left side, you can see the mapping source. In this case, the source is the Self context of the related class. If the mapping operation has input parameters, the mapping diagram will also show elements in the Input section of the mapping diagram.
On the right side, you can see the mapping target (section Output). The target is defined by the output parameters of the mapping operation.

Refer to the other pages in this chapter for more information on how to model a valid Mapping diagram:
