I am still new to ABAP programming and have written a small program as a calculator.
This calculator has a table in the background as a history. This history (SALV table) should be output using the “Tabelle anzeigen” button. So far the whole thing works.

Now I have added my own button and it only loads the salv table up to a certain entry and then gives a runtime error.

I have already found out that it is due to the EXPORTING r_container = cl_gui_container=>default_screen.
But I have no idea how to fix the problem.

Thank you for your help.
