How to import a range in Function module?

Question

I am using a Function module in which material is getting imported.
In the import tab we have
Parameter Name    Typing     Associated Type       optional          pass value
IM_MATERIAL       TYPE       MATNR                 <checked>         <checked>
So when the Function module is execute we can enter only one value into the IM_MATERIAL.
But now it has to be enhanced for entering multiple values. How to import the material as a range?
Please throw light.
Thanks.

Hi
If you are using a select-options you can use this approach.
TABLES: MARA.
DATA: RANGE TYPE WRF_MATNR_RANG_TTY.
SELECT-OPTIONS: SO_MATNR FOR MARA-MATNR.
START-OF-SELECTION.
  RANGE[] = SO_MATNR[].
CALL FUNCTION 'ZTEST'
EXPORTING
   I_RANGE       = RANGE.
Where I_RANGE is defined using this table type WRF_MATNR_RANG_TTY
Parameter Name    Typing     Associated Type     optional          pass value
I_RANGE       TYPE       WRF_MATNR_RANG_TTY      <checked>     <checked>
