Hi Phillip,
debugger usually starts with the MAIN window and not necessarily from top to bottom.
Going through until you reach your window per F5 can be tedious.
The easiest way to make the debugger stop at the position you need: Uncheck everything at the startscreen of the SAPSCRIPT-Debugger (Warning Messages etc.) and in "Text element", enter the corresponding text element (the /E line).
If you don't have any text element in the HEADER window, you could enter "PERFORM" (without the "") in the "Command" field. Then, skip to your position per F8.
Kind regards
Matthias
