While you are debugging your program, you can save the content of an internal table.
- Display the content of the internal table in the debugger.
Then press ctrl-F11 or right-mouse and click "Save As Excel Worksheet".
Enter the From-index and To-index for the lines you want to save.
Choose folder/filename and save.
This is available from 4.7 onwards, however, for those of you that are not yet on 4.7:
In 4.6, once you have displayed the content of internal table:
Goto->Display data object->Structure editor
If not all rows are displayed.
Object-Display full list.
System->list->save -> Local file
