Hi.
The Select statment accessing MSEG Table is Slow Many a times.
To Improve the performance of  MSEG.
1.Check for the proper notes in the Service Market Place if you are working for CIN version.
2.Index the MSEG table
2.Check and limit the Columns in the Select statment .
Possible Way.
SELECT MBLNR MJAHR ZEILE BWART MATNR WERKS LIFNR MENGE MEINS
EBELN EBELP LGORT SMBLN BUKRS GSBER INSMK XAUTO
FROM MSEG
INTO CORRESPONDING FIELDS OF TABLE ITAB
WHERE WERKS EQ P_WERKS AND
MBLNR IN S_MBLNR AND
BWART EQ '105' .
Delete itab where itab EQ '5002361303'
