Question: If a program (eg.: ZXYZ) calls a function module, can I access memory variables that are available in ZXYZ, but are not passed to the function module?

Answer:Yes!!!

Here is a sample code to access an internal IT_DATA from ZXYZ

===============
DATA: var_name(30) TYPE c VALUE ‘(ZXYZ)IT_DATA[]’.

TYPES: BEGIN OF st_data,
**** The same definition as IT_DATA in program
END OF st_data.

DATA: wa_data TYPE st_data.

FIELD-SYMBOLS: TYPE ANY TABLE.

ASSIGN (var_name) TO .

LOOP AT INTO wa_data.

WRITE : / wa_data.

ENDLOOP.
