Hi guys,
This is my first blog and I found an interesting subject one week ago about RoadMap but in GUI environment, normally Roadmap is used with Web Dynpros.
This is the code of my program

Here I attach screen 100 to upload and generate
Then when you execute the program you can select how many steps are going to build, for example I'll select 10
And this is the result
You can click on any step or press "Next Step" button to select the next step, I hope this help you in any development and I welcome your comments
PD: Sry for my bad english
