rfc function module issue

[former_member1311160]

hi ,

i created a rfc function module with export , import and changing parameters.

In changing parameter i gave as cd_kunnr type kunnr  passbyvalue.

and then i wrote select statement

   SELECT SINGLE kunnr  INTO lv_kunnr

     FROM kna1

     WHERE kunnr = cd_kunnr.

am passing  kunnr from other system  as

CALL FUNCTION 'Z30FM_RECKAUF_LOG' DESTINATION lv_dest

  EXPORTING

    store                       = lv_store

* IMPORTING

*   VKORG                       =

*   VTWEG                       =

   CHANGING

     kunnr                       =  lv_kunnr

  EXCEPTIONS

    no_data_found               = 1

    no_customer_for_vkrog       = 2

    OTHERS                      = 3

here am not getting value to cd_kunnr .

can any one help me ?

Hi,

I'm not sure what you mean. Your custom RFC is not returning a value in lv_kunnr?

If not, have you tried debugging it?

cheers

hello paul ,

my rfc function module is not receiving the values which i passed from other system . so my select statement is failing .

when i debug there is no value in cd_kunnr .

Without knowing anything about what is going on inside the FM, it's hard to say, but you could try SELECTing using KUNNR rather than LV_KUNNR in the WHERE clause.

Hi,

As far as I know changing parameter cannot be used inside an RFC.  Try with export and import parameters. This is because RFC can be called outside the SAP System Landscape.

Please refer the below thread.
