I have function module say ZFUNC and main program say ZMAIN and internal table defined as IT_TAB inside ZMAIN but not passed as parameter to Function module ZFUNC.
If I want to access the field value of IT_TAB of main program ZMAIN inside ZFUNC during debugging then, I simply put <b>(ZMAIN)IT_TAB-amount</b> in ABAP debugger and then change it when the debugger is inside ZFUNC.
How can I write code to change the value of internal table of main program in function module ZFUNC instead of doing in debugger ? I guess I have to use some field symbols, but not sure. Please suggest.
