Visual Abap is a Web tool for creating abap selection screens : This tool is useful for documenting new abap reports on the analysis and design phase.
Easily you can create a selection screen with the most common abap objects (blocks, parameters, select-options, …) . When you’ve designed the selection screen, you could capture the screen to make the documentation.
Next steps should be the abap code generation from this selection screen . It will be the beginning of Visual Abap!
