Using Subscreens on Report Selection Screens

This report shows an example of how to have a tabbed selection screen as part of your report selection screen. This is done using subscreens, and is only available in the 4.X series (I have only tested it on 4.6 systems).

This example is the start of a BDC program, and separates the different selection criteria onto different pages.

Code:
report tabbed_sel_screen.
*-- Definitions to hold user command for subscreens
data:
  ucomm1 like sy-ucomm,
  ucomm2 like sy-ucomm,
  ucomm3 like sy-ucomm.
*-- Macro to put checkbox on selection screen
*-- &1 - checbox parameter name
*-- &2 - text element (description)
*-- &3 - default value for checkbox
define make_checkbox.
  selection-screen begin of line.
  parameters: &1 as checkbox default &3.
  selection-screen comment 3(60) &2.
  selection-screen end of line.
end-of-definition.
*-- Macro to put radiobutton on selection screen
*-- &1 - radiobutton parameter name
*-- &2 - text element (description)
*-- &3 - radiobutton group
define make_radiobutton.
  selection-screen begin of line.
  parameters: &1 radiobutton group &3.
  selection-screen comment 3(60) &2.
  selection-screen end of line.
end-of-definition.
*-- Macro to put a parameter on selection screen
*-- &1 - parameter name
*-- &2 - text element (description)
*-- &3 - like data element
*-- &4 - default value
define make_parameter.
  selection-screen begin of line.
  selection-screen comment 1(30) &2.
  selection-screen position pos_low.
  parameters: &1 like &3 default &4.
  selection-screen end of line.
end-of-definition.
*-- Macro to put a dropdown listbox on selection screen
*-- &1 - parameter name
*-- &2 - length of listbox
*-- &3 - default value
*-- &4 - text element (description)
define make_dropdown.
  selection-screen begin of line.
  selection-screen comment 1(30) &4.
  selection-screen position pos_low.
  parameters: &1 as listbox visible length &2 default &3 obligatory.
  selection-screen end of line.
end-of-definition.
*-- Define subscreen for upload options
selection-screen begin of screen 1100 as subscreen.
selection-screen begin of block file_options with frame.
make_parameter   p_filein fil_desc rlgrap-filename '/filename.txt'.
make_radiobutton rb_unix  unx_desc src.
make_radiobutton rb_local dos_desc src.
make_parameter   p_filety typ_desc rlgrap-filetype 'DAT'.

make_dropdown    p_uptyp(1) 30 'S'  upd_desc.
selection-screen end of block bdc_options.
selection-screen end of screen 1200.
*-- Define subscreen for Output Options
selection-screen begin of screen 1300 as subscreen.
selection-screen begin of block output_opts with frame.
make_checkbox c_detail det_desc ' '.
make_checkbox c_error  err_desc 'X'.
make_checkbox c_stats  sta_desc 'X'.
selection-screen end of block output_opts.
selection-screen end of screen 1300.
*-- Define Main Selection screen that will incorporate the subscreens
selection-screen begin of tabbed block tabs for 10 lines.
selection-screen tab (15) tabs1 user-command ucomm1
 default screen 1100.
selection-screen tab (30) tabs2 user-command ucomm2
 default screen 1200.
selection-screen tab (15) tabs3 user-command ucomm3
 default screen 1300.
selection-screen end of block tabs.
*-- Fill the dropdown list boxes before displaying them
at selection-screen output.
  perform fill_dropdown_list using 'P_MODE'.
