Cannot select the fields for table view WB2_V_MKPF_MSEG2

Question

Hi, I have a program where the query is using join statement of MSEG and MKPF.  As part of the performance enhancement I use Table View WB2_V_MKPF_MSEG2 instead.
Validation: Entries in MSEG and MKPF is the same as in  WB2_V_MKPF_MSEG2 = OK (via SE16)
But upon debugging the program on SY-SUBRC breakpoint, I can see 5 rows appended in internal table T_MSEG "BUT" the entries are all blank.
The entries in my SE16 are exact data that's appearing on the filter statement in my SQL query below.  SE16 is giving correct output, but using table view in my SQL does not give me the correct output.
(Note: This is my first time to use table view in ABAP-SQL)
  SELECT MATNR_I BWART_I MENGE_I
    FROM  WB2_V_MKPF_MSEG2
      INTO CORRESPONDING FIELDS OF TABLE T_MSEG
  WHERE MATNR_I IN R_MATNR3
      AND  MATNR_I IN R_COMPNTS
      AND  WERKS_I EQ P_WERKS
      AND  BWART_I EQ '931'
     AND  BUDAT    IN S_GSTRP 
     AND  MJAHR    EQ W_DOC_YEAR.
IF SY-SUBRC EQ 0.
ENDIF.
THANKS, appreciate your inputs.

Hi Suhas,
I just did a short test just now:
REPORT  ZTEST_SELVIEW.
TABLES: WB2_V_MKPF_MSEG2.
TYPES: BEGIN OF Y_MSEG,
         MATNR LIKE MSEG-MATNR,
         BWART LIKE MSEG-BWART,
         MENGE LIKE MSEG-MENGE,
       END   OF Y_MSEG.
DATA: T_MSEG TYPE STANDARD TABLE OF Y_MSEG.
SELECT MATNR_I
       BWART_I
       MENGE_I
  FROM WB2_V_MKPF_MSEG2
  INTO CORRESPONDING FIELDS OF TABLE T_MSEG
WHERE MATNR_I EQ '000000000000004000'
   AND WERKS_I EQ '0288'
   AND BWART_I EQ '931'
*   AND BUDAT   EQ '20071117'
   AND MJAHR   EQ '2007'.
IF SY-SUBRC EQ 0.
ENDIF.
In my debug, T_MSEG contains the same number of rows that my SE16>WB2_V_MKPF_MSEG2(using the hard coded statement in my SQL) "BUT" each rows does not have any entries.  Bottomline, I can't only see blank entries in ITAB T_MSEG but the rows are being selected properly, so the itab contains x-number of rows with blank entries.
Thanks.
