I am working through the Developer course program, and somewhere along the line i had messed up work i did in T210 while working through T220. I couldnt figure out the problem after many hours, and decided it best to just start over with a fresh T220 install using the Acumatica ERP Configuration tool. 

It doesnt seem to have worked properly. With a fresh install, when trying to click the Services and Prices, it says

‘ Error: A site map node with the screen ID RS203000 does not exist. Maybe it was moved or removed.

 

But i can manually change the url to go directly to the screen. My Site Map has RS203000 on it. Its a screen in my customization project browser. Its included on the Site Map of the customization project. Its included in the Access Rights. 

 

Any guidance would be appreciated

Which build of 2025 R2 do you use? We recommend that you complete the courses on the latest version, which is 2026 R1. You can find the guide for this version here.
