Use
The Enhancement Builder is a collection of individual tools for creating and maintaining enhancement spots and enhancement implementations, and their administration. The tools of the Enhancement Builder are called by forward navigation from within the other ABAP Workbench tools. In addition, there are special tools for navigation and administration.
Besides defining enhancement options for Repository objects, which can be enhanced within the enhancement concept, and the related actual enhancements, you can edit enhancement spots and enhancement implementations in the Enhancement Builder.
