SELECT-OPTION to internal table

Hi,

I need to convert the select-option values into an internal table.

For example, if there is a select-option S_WERKS... i need all the values entered for S_WERKS into the internal table. The internal table structure contains only WERKS.

My actual requirement is, for the given plant values as select-option, i need to fetch all details of the plants. And I should not use any SELECT statements at any stage. Only through function module/ BAPI/BADI/Class methods.

I found one function module T001W_READ, but i need to pass the plant for that.

Please suggest.

Thanks in advance.
