Using select options to select records

SELECT-OPTIONS:    S_CPUDT FOR BKPF-CPUDT DEFAULT SY-DATUM,
            S_USNAM  FOR BKPF-USNAM.


SELECT * FROM  BKPF
    WHERE    CPUDT IN S_CPUDT AND

USNAM IN S_USNAM.

Select options with more than one default value or range

If you want to use more than one default value or default range, you add the values to the internal table selection table.

Note: You don't have to declare the table, it is created automatically. The table has the same name as the select variable ( In the example below s_hkont ).

SELECT-OPTIONS: S_HKONT FOR ZTSAPSPEC-HKONT.
                            

INITIALIZATION.
  MOVE: 'I' to s_hkont-sign,
               'BT'  TO  S_HKONT-OPTION,
               '87111100' TO S_HKONT-LOW,
               '87111124' TO S_HKONT-HIGH.
  APPEND S_HKONT.
  MOVE: 'I' to s_hkont-sign,
               'EQ'  TO  S_HKONT-OPTION,
               '87111300' TO S_HKONT-LOW,       
  APPEND S_HKONT.                             

Making a frame around groups of fields on the selection screen.

SELECTION-SCREEN BEGIN OF BLOCK 1 WITH FRAME TITLE TEXT-001.

SELECT-OPTIONS: S_CPUDT  FOR BKPF-CPUDT OBLIGATORY
                                            DEFAULT SY-DATUM.
SELECTION-SCREEN END OF BLOCK 1.

You can add further blocks (block2.......)

Making a checkbox

parameters: x_afstem as checkbox default 'X'.

Making a radiobutton group

PARAMETERS:    <Name of button> RADIOBUTTON GROUP <name of group >,
        <Name of button> RADIOBUTTON GROUP <name of group>.

Example:

PARAMETERS: BUTTON1 RADIOBUTTON GROUP RAPT,
                            BUTTON2 RADIOBUTTON GROUP RAPT.


In the program you test for the radiobuttons like this:

if button1 = 'X' then.
 < Here comes some code>
elseif button2 = 'X' then.
 < Here comes some code>
endif.

How to add an option after the user has finished the selection screen

Use the at selection-screen event to add options as showed above in example 2.
 

Selection screen events

Making an option invisible        

If you don't want the user to be able to see the option you want to add, define it as No-DISPLAY.

SELECT-OPTIONS:    S_HKONT FOR ZTSAPSPEC-HKONT NO-DISPLAY,
        S_BUKRS FOR ZTSAPSPEC-BUKRS,

Selection screen - Parameters on a single line   

SELECTION-SCREEN BEGIN OF LINE.                                     
*   The system does not output selection texts for parameters.      
*   Set your own                                                    
    SELECTION-SCREEN COMMENT 1(15) text-001.                        
*   Parameters                                                      

    PARAMETERS: p1(3) TYPE c,                                       
                                p2(5) TYPE c.                                       
   SELECTION-SCREEN COMMENT 55(10) p_wmunit.                        
                                                                    
SELECTION-SCREEN END   OF LINE.                                     

INITIALIZATION.                                                     
  MOVE 'Unit' TO p_wmunit.                                          

                                                                    

Setting the title text of a selection screen dynamically

Define GUI titles for the report. In this example the GUI titles COLLILABEL
and PALLETLABEL has been defined. In the INITIALIZATION event, dynamically
set which GUI title to show with the SET TITELBAR statement.

                                   
INITIALIZATION.                    
  IF p_colli = 'X'.                
    SET TITLEBAR 'COLLILABEL'.     

  ELSEIF p_pallet = 'X'.           
    SET TITLEBAR 'PALLETLABEL'.    
  ENDIF.                           

Using a custom toolbar in a selection screen

When you use your own custom toolbar in a selection screen, the flow of the
report changes. Below is an example of how to use the events in such a
report.

Important! To be abel to submit your report, the submit button on the custom
toolbar of the selection screen must be named
 'ONLI'  (= Execute)  or 'PRIN'  (= Execute and Print). 

INITIALIZATION.            
* Your custom toolbar for the selection screen
  SET PF-STATUS '0002'.    

AT SELECTION-SCREEN. 
* Handle sy-ucomm from your custom toolbar on the selection screen. Note
that it is not necessary explicitly to handle 'ONLI' or 'PRIN'
  CASE sy-ucomm.     
    WHEN 'GETDATA'.  
    WHEN 'EXIT'.     
      LEAVE PROGRAM. 
  ENDCASE.           


START-OF-SELECTION.                              
  ..... retreieve data for the ereport.....

END-OF-SELECTION.                 
* PF status for the report 
  SET PF-STATUS '0001'.                          
 ..... write report ......                                
 

Skip line on selection screen

Selection-screen skip 1.
