Accessing internal table of main program inside function module...

[Former Member]

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.

Yes, you do need to use a field symbol. Say for example, you had a internal table called IMARC in your program and you want to access it later in a funciton module, you would do something like this.

  data: xmarc type marc.
  field-symbols: <imarc> type marc_upl_tt.

* Assign an internal table
  field = '(ZPROGRAM_NAME)IMARC[]'.
  assign (field) to <imarc>.

  loop at <imarc> into xmarc.
    write: / xmarc-matnr, xmarc-werks.
  endloop.

The above solution will help me seeing the value but if I wanna change the value of (ZMAIN)I_TAB-amount inside function module how can I do that ?

Well, since you use a field symbol, this will give you access to the internal table, You can then read the specific line that you want to change, and update is using a MODIFY statement.
