select option problem

HI experts,

i am developing bsp selection screen , where i got problem regarding the select option.

Is it possible to use the IN operator in bsp.

like MATNR from -

.

so i can use to fetch data like following.

select * from mara where matnr in MATNR.

Now i have taken 2 variables and using between operator to fetch data.

select * from mara where matnr between matnr1 and matnr2.

If possible can some one tell me.
