Correct FM called when testing delta?

Question

Hi all, I have created a copy of the RSAX_BIW_GET_DATA which is used by my extractor. Full load is working good.
First I triggered a init from BW, then debugged the delta from RSA3.
The program did not use the FM I created (ZRSAX_BIW_GET_DATA), but instead the FM RSC1_DELTA_BIW_GET !
Is that correct? I expected my Z FM to be called.
Any suggestions?

Hi, the FM I have created is a copy from the RSAX_BIW_GET_DATA.
The FM have some logic to test delta, and some logic to select data from the database.
When I debug, the first init call is correct. Then <b>S_FNAME</b> have the value for my FM name ZRSAX_BIW_GET_DATA:
    CALL FUNCTION <b>S_FNAME</b>
         EXPORTING
              I_REQUNR                     = S_S_IF_SIMPLE-REQUNR
              I_DSOURCE                    = S_S_IF_SIMPLE-DSOURCE
              I_MAXSIZE                    = S_S_IF_SIMPLE-MAXSIZE
              I_INITFLAG                   = S_S_IF_SIMPLE-INITFLAG
         TABLES
              I_T_SELECT                   = S_S_IF_SIMPLE-T_SELECT
              I_T_FIELDS                   = S_S_IF_SIMPLE-T_FIELDS
         EXCEPTIONS
              NO_MORE_DATA                 = 1
              ERROR_PASSED_TO_MESS_HANDLER = 2
              OTHERS.
But then, in the <b>second call</b> to fetch data, the field <b>l_fname</b> has the value RSC1_DELTA_BIW_GET:
by field ROIS-GENFLAG
    IF ( p_s_request-updmode = sbiwa_c_updmode_delta
      OR p_s_request-updmode = sbiwa_c_updmode_repeat
     OR p_s_request-updmode = srsc_c_updmode_initsimu       "30BSP07
      OR p_s_request-updmode = sbiwa_c_updmode_deltainit ).
      CALL FUNCTION <b>l_fname</b>
        EXPORTING
          i_requnr                     = p_s_request-requnr
        TABLES
          e_t_data                     = l_t_ZBW_STRCT_RJ_TEST1
        EXCEPTIONS
          no_more_data                 = 1
          error_passed_to_mess_handler = 2.
I want my FM name ZRSAX_BIW_GET_DATA to be in the second call as well..
