Interval in the module pool selection screen

Question

Hi Experts,
   I am creating selection screen in module pool program. I know how to set search help for each field.
But if I have select-options like fields, how can I have "Interval button". Is there any fuction module for that? should I use ranges?
Thanks and regards,
Venkat

Hi,
Follow these steps:-
To implement select-options in module pool, first design two input/output fields (textboxes) for the low and high value of the field and name it as <field_name>-low and <field_name>-high.
Create a button next the high value textbox and keep its sutaible function code.
Now, to call the pop-up on this button click, we have to call the same pop-up as in standard      select-options. For this we have to use the function module COMPLEX_SELECTIONS_DIALOG.
For this FM we have to pass the table name, field name and the range for the field whose range needs to fill when using the popup screen.
To pass the table name and field name details into the FM, we have to declare as:
DATA : tab TYPE rstabfield.
This structure comprises of table name and field name.
Pass these details in program as:-
u2003
*-- clear table and field details
  CLEAR tab.
*-- append for range depending on the button clicked
*   either for sales order or line item
  CASE sy-ucomm.
    WHEN 'VBELN'.
      tab-tablename = 'VBAP'.
      tab-fieldname = 'VBELN'.
*--To call the popup screen for the field use code:-
  CALL FUNCTION 'COMPLEX_SELECTIONS_DIALOG'
    EXPORTING
      title             = text-002  u201Ctitle text
      text              = ' '
      signed            = 'X'
      search_help       = v_shelp u201Csearch help if required
      tab_and_field     = tab u201Ctable and field name details
    TABLES
      range             = r_vbeln u201Crange for the associated field
    EXCEPTIONS
      no_range_tab      = 1
      cancelled         = 2
      internal_error    = 3
      invalid_fieldname = 4
      OTHERS            = 5.
Hope this helps you.
