Variant configuration call Funktion - E28021 Error

[schneidermi]

Hi,

I have created an variant function accordingt to the blog https://blogs.sap.com/2015/05/31/variant-functions-with-an-example/

When i try to create the Dependency and call the Function Module in Procedure-Editor, I get the following Error:

E28021 Error: remaining part of expression cannot be interpreted (Line 10)

Sourcecode:

PFUNCTION Z_FM_VC_TEST
( GI_BR_TX = 12).

I don't understand what the problem is?

what have I done?

Step 1

Creation of the VC-Function and the Function Module of the same name Z_FM_VC_TEST using Transaction cu65/66

VC-Function:

assigned characteristics

Source code of Function Module

FUNCTION Z_FM_VC_TEST
  IMPORTING
    GLOBALS LIKE CUOV_00
  TABLES
    QUERY LIKE CUOV_01
    MATCH LIKE CUOV_01
  EXCEPTIONS
    FAIL
    INTERNAL_ERROR.


  CALL FUNCTION 'CUOV_GET_FUNCTION_ARGUMENT'
    EXPORTING  argument      = 'GI_BR_TX'
*  IMPORTING
*               vtype         = " Value format
*               sym_val       = " Alphanumeric value
*               num_val       = " Numeric value
*               io_flag       = " Input/output parameter indicator
    TABLES     query         = query                " Table of input and output parameters
    EXCEPTIONS arg_not_found = 1                " Parameter not found
               OTHERS        = 2.
  IF sy-subrc <> 0.
  ENDIF.

ENDFUNCTION.

Step 2

Create Dependency Procedure using Transaction CU01.

Sorcecode

* set the default value if not given
$SET_DEFAULT ($SELF, GI_BR_TX, 1).

* PFUNCTION Z_FM_VC_TEST($ROOT).
* FUNCTION Z_FM_VC_TEST (
* GI_BR_TX = 12
* )

PFUNCTION Z_FM_VC_TEST
( GI_BR_TX = 12
 ).

I've tested
FUNCTION Z_FM_VC_TEST
and also
PFUNCTION Z_FM_VC_TEST

Thanks a lot.

Hi schneidermic,

actually, pfunction can be called without parameters, so this should work:

PFUNCTION  ZFM_SD_VC_GET_CHARCTERISTIC().

hope this will fix the error

Thanks and bye,
