Screen enhancement with table control

Question

Dears,
I'm using enhancement IWO10018 to add a new tab on IW32 screen. I've added a table control to this tab. The problem is that retreived data from database do not appear on the table and it is appeared as empty fields. When tring to add any other input/output field on the same subscreen the data appear correctly on it! Please advise

  LOOP AT req_itab
    WITH CONTROL serv_req_tab.

  ENDLOOP.
MODULE fill_req_itab OUTPUT.
  CLEAR: req_itab[].
  SELECT * FROM zcs_serv_req
    INTO CORRESPONDING FIELDS OF TABLE req_itab
    WHERE aufnr = order_no.

Thanks a lot for your reply...
I've added the below code on the mentioned include and I've commented it on the PBO but I still have the same problem. On debug mode I can see that required data retreived correctly till end.
*&  Include           ZXWOCU15
order_no = sap_caufvd_imp-aufnr.
CLEAR: req_itab[].
  SELECT * FROM zcs_serv_req
    INTO CORRESPONDING FIELDS OF TABLE req_itab
    WHERE aufnr = order_no.
