hi,

first of all create a strucutre in se11. this structure is similar to your internal table then declare the importing/exporting parameter with that structure type

thanks

Hi Neha,

Incase you want a function module interface table with fields from different DB tables, then create a structure in a type pool from SE11 and include the type pool in the main program (TOP include) of your function group.

Then you can use the structure as a TYPE decleration in your function module.

However if your function module is RFC enabled, then it is not possible to use type pool structures and you must create a structure in SE11 data dictionary level.

Hi,

if you do not want to do the DDIC work and you remain inside your system (no RFC), you can use a reference variable of TYPE REF.

Calling program:

data:
  l_ref type ref to data.
  get reference of itab into l_ref.
call function 'ZXY'
  exporting 
    REF = l_ref
* ...
*
In the function:

field-symbols:
  <itab> type table.
assign REF->* to <itab>.
*...

For the sake of transparency, it is definitely better to create a structure and a table type with the stzructure as line type in data dictionary. But if you want flexibility, the passing of reference variables is a good method.
