BAPI_COSTCENTER_CHANGEMULTIPLE with Initial Value

Hi All,

   I am trying to update Cost Centers using BAPI_COSTCENTER_CHANGEMULTIPLE.  It is working as expected with the fields are having values.  If I change one field value to INITIAL, it is retaining the old value after the updation.  The case is same with both the normal fields and the custom additional fields.

  I could see that it is happening in  K_COSTCTR_BAPI_CHECKMULTIPLE -----> CALL METHOD go_application->change -----------> CALL METHOD lcl_services=>make_struct_to_fvtab. 

IF ( NOT p_keep_empty_fields = true AND

            <source> IS INITIAL ).

         CONTINUE.

       ENDIF.

Here  p_keep_empty_fields is always true and when the field is Initial, this condition is true and the rest of the code is skipped.  Any work around is highly appreciated.

Regards,

Asha
