Build a select option based on values from internal table

Hello ,

Is there a way, I can dynamically populate the select option, with values from an internal table ? I guess there must be a function module available for this.

For eg, say I have t_kna1 table with values like,

1,2,3,4,5,6,10,15,18,19,20,21,22,23 and 30.

Once I pass this internal table, it should populate the select options with low, high values as below.

Sign Option Low HIGH

-

I BT 1 --- 6

I EQ 10

I EQ 15

I BT 18 --- 23

I EQ 30

any guidance appreciated.

Thanks much
