Stock on particular date (performance issue)

Question

Hi Folks,
I m calculating stock at all vendor on a particular date.
But it takes very long and time_out occurs.
I m calculating opening closing provided return and rejection based on movement types.
The report hangs up at following particular Join.
SELECT MKPFBUDAT MSEGBWART MSEGMATNR MSEGLIFNR SUM( MSEG~MENGE )
              AS MENGE
                  INTO CORRESPONDING FIELDS OF TABLE IT_OPEN
                  FROM
                     MKPF INNER JOIN MSEG ON
                           MKPFMBLNR = MSEGMBLNR AND
                           MKPFMJAHR = MSEGMJAHR
                   WHERE MKPF~MJAHR = D_YEAR AND
                         MKPF~BUDAT GE D_DATE AND
                         MKPF~BUDAT LT S_BUDAT-LOW AND
                MSEG~BWART IN ('541','542','543','544','551','702') AND
                         MSEG~XAUTO NE 'X' AND
                         MSEG~MATNR IN S_MATNR AND
                         MSEG~WERKS IN P_WERKS AND
                         MSEG~LIFNR IN P_LIFNR
              GROUP BY LIFNR MATNR BUDAT BWART.
Is there any way to increase performance by breaking this inner join into select statements or anyhow.
Regards

HI,
On seeing your code, it seems like,
SELECT MKPFBUDAT MSEGBWART MSEGMATNR MSEGLIFNR SUM( MSEG~MENGE )
AS MENGE
INTO CORRESPONDING FIELDS OF TABLE IT_OPEN
FROM
MKPF INNER JOIN MSEG ON
MKPFMBLNR = MSEGMBLNR AND
MKPFMJAHR = MSEGMJAHR
WHERE MKPF~MJAHR = D_YEAR AND
MKPF~BUDAT GE D_DATE AND
MKPF~BUDAT LT S_BUDAT-LOW AND
MSEG~BWART IN ('541','542','543','544','551','702') AND
MSEG~XAUTO NE 'X' AND
MSEG~MATNR IN S_MATNR AND
<b>MSEG~WERKS EQ P_WERKS</b> AND
<b>MSEG~LIFNR EQ P_LIFNR</b>
GROUP BY LIFNR MATNR BUDAT BWART.
Please see the code marked with bold as parameter passing in the select statement must be EQ and not IN.
Secondly, remove the aggregate function SUM from the select. First select all the records into an internal table and either use control break statements or Collect to sum up the entries.
Next, while selecting from the database use INTO TABLE IT_OPEN rather than into corresponding fields of table.
Also remove the movement types from the select and restrict it inside the Loop and Endloop.
