Generic function module call; Tables parameters

[VolkerProebius]

Hallo,

I'm trying to run a generic function module call

like:

**Call of function module  **************************

  TRY.

      CALL FUNCTION gv_function_module

        PARAMETER-TABLE lt_parms[]

        EXCEPTION-TABLE lt_exception[].

    CATCH cx_sy_dyn_call_illegal_func.

    CATCH cx_sy_dyn_call_error.

*      MESSAGE ...

      EXIT.

  ENDTRY.

  It works fine for importing and exporting parameters but I don't know how to read the

  tables returned by the function module.

  Thanks a lot for your help !

  Example: If you see the signature of FM BAPI_MESSAGE_GETDETAIL below I can fill all importing parameters,

  getting back the exporting parameters but how to get the tables parameters ?

  FUNCTION BAPI_MESSAGE_GETDETAIL.

Hi,

In ABAP editor, there's an option 'Pattern'. Use that to call any FM/BAPI. Click on 'pattern' and enter FM. Un-comment required parameters under import/export/tables.

If you just read the documentation, you will have the answer -> http://help.sap.com/abapdocu_702/en/?url=ABAPCALL_FUNCTION_DYNAMIC.htm

Sorry, I understand your point. But it has been discussed many times in the forum :

First, see the answer of Tomas Buryanek about the required CREATE DATA before doing the CALL FUNCTION

Then the CALL FUNCTION

Then analyze the returned value of the internal table

FIELD-SYMBOLS <itab> TYPE standard table.

FIELD-SYMBOLS <line> TYPE any.

FIELD-SYMBOLS <field> TYPE any.

ASSIGN ref->* TO <ITAB>.

LOOP AT <itab> ASSIGNING <line>.

ASSIGN COMPONENT 1 OF STRUCTURE <line> TO <field>. " assuming line is a structure

ENDLOOP.

TABLES parameter works as both importing and exporting parameter.

So you need to prepare an entry in PARAMETER-TABLE for it:

DATA mara TYPE mara_tt.
DATA: lt_par_tab TYPE abap_func_parmbind_tab,
      ls_par_tab LIKE LINE OF lt_par_tab,
      lref_mara TYPE REF TO data.

CREATE DATA lref_mara LIKE mara.

ls_par_tab-name = 'MARA'.
ls_par_tab-kind = abap_func_tables. " = '30'
* ls_par_tab-value = lref_mara.
* EDIT: better this way, without lref_mara:
GET REFERENCE OF mara INTO ls_par_tab-value.
INSERT ls_par_tab INTO TABLE lt_par_tab.

CALL FUNCTION 'ZTEST_TABLE_RETURN'
  PARAMETER-TABLE lt_par_tab.
"Interface:
* TABLES
*   MARA          = MARA.
