delete statement error.

Hi,

    In final internal table am having 10 records,

mat no           ebeln           ebelp           bwart           grund           menge

1                    013445          1               541               18               25

2                    013445          1               101               18               25

3                    013445          1               542               18               25

4                    013445          1               542               18               25

5                    013445          1               544               18               25

6                   013445           1               543               18               25

above records i want to separate the values based on bwart..so am using

DELETE GT_FIN_102 [] WHERE BWART_I NE '102' OR BWART_I NE '544' .

DELETE GT_FIN_101 [] WHERE BWART_I NE '101 OR BWART_I NE '543' .

but it deletes all the internal values by using OR condition.

May i know how to use delete statement with multiple conditions.????/
