Difference b/w At-selection-screen and onfield

Hi,
What is the difference between at-selection-screen and at-selction-onfield?

Different Types of Selection Screens
What is:
1. at selection-screen on field
2. at selection-screen output
3. at selection-screen block
4. at selection-screen on value-request
5. at selection-screen on help-request and their difference?
For knowing Selection-screens:
First you must have right understanding of Events.
- Events are introduced by Event Keyword. They end when again next processs begins.
Selection-screens are special screen defined in ABAP.
- This ABAP at run time only controls the flow logic of Selection-screens. The PBO and PAI triggers the num of. selection-screens.
The basic form of the selection screen events is the AT SELECTION-SCREEN event. This event occurs after the runtime environment has passed all input data from the selection screen to the ABAP program. The other selection screen events allow programmers to modify the selection screen before it is sent and specifically check user input.
At Selection-screen OUTPUT is trigerred in PBO of selection-screen.
- This allows you to modify the Selection-screen, before it is displayed.
At Selection-screen On Field is triggered in PAI of selection-screens.
- The input fields can b checked,in the corresponding event block. If an error message occurs within this event block, the corresponding field is made ready for input again on the selection screen.
At Selection-screen On Block is trigerred in PAI event.
- You define a block by enclosing the declarations of the elements in the block between the statements SELECTION-SCREEN BEGIN OF BLOCK block - END OF BLOCK block. You can use this event block to check the consistency of the input fields in the block.
At Selection-screen On value request.
- This event is trigerred for F4 help.
At Selection-screen On help request .
- This event is triggered when the user clicks F1 for help on fileds.

Hi,
AT SELECTION-SCREEN is the event triggered in the PAI of the selection screen.
AT SELECTION-SCREEN on field field_name is the event specific to the field and is triggered when u press enter in that field.
AT SELECTION-SCREEN selscreen_event.
Effect
This statement defines event blocks for different events selscreen_event that are triggered by the ABAP runtime environment during selection screen processing.
Selection screen events occur immediately before sending a selection screen and after certain user actions on a displayed selection screen. They assist in selection screen processing in the ABAP program.
AT SELECTION-SCREEN is triggered at least twice during actions on selection screens that are linked into another selection screen as a subscreen - first for the linked selection screen itself, and then for the linking selection screens.
SELECTION-SCREEN FIELD SELECTION
FOR {NODE|TABLE} node [ID id].
Effect
This statement defines a node node in the structure of the logical database for field selection. If a node belongs to type T, you can use the TABLE addition instead of NODE. The statement cannot be used for type C nodes. .
If a node is defined for field selection, you can use an executable program linked to the logical database in the GET statement to control which fields in the node are to be read by the logical database. If you use the function module LDB_PROCESS, the FIELD_SELECTION parameter must be specified accordingly.

Background Processing, Selection Screens and Variants

Hi All,
I am having a little trouble Background Processing with Selection Screens and Variants.
When a user runs my report and selects the option of background processing, then they select a checkbox. Once this is checked, they should go and fill in details, press Execute and voila a background process is created. However what is happening is that when i execute it then it asks for a variant. I do not want this to happen. I want the values in the selection screens to be used as default. Here is my code for background processing
FORM START_BACKGROUND_PROCESSING.
CALL FUNCTION 'BP_JOBVARIANT_SCHEDULE'
    EXPORTING
      TITLE_NAME            = 'End Customer Report '
      JOB_NAME              = 'customer_report'
      PROG_NAME             = 'ZSE_SD_SALES'
EXCEPTIONS
    NO_SUCH_PROGRAM       = 1
    OTHERS                = 2
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
ENDFORM.                    "START_BACKGROUND_PROCESSING
After the background process is started, all teh data is collated then written to the app server. this is the order
ELSEIF R2 EQ 'X' AND SY-BATCH EQ 'X'.
    PERFORM INITIALIZE_DATA.
    PERFORM SELECT_DATA.
    PERFORM PROCESS_DATA.
    PERFORM GET_END_CUSTOMER_DATA.
    PERFORM WRITE_TO_APP_SERVER.
Any ideas? Points given to those who are helpful

Selection-screen and GET

Hi all,
in my program i use PNP logical database, so system create automatically selection screen. Nice.
When user fill selection screen event start-of-selection is launched and i do GET PERNR for read data from PNP.
But my customer want to add field in selection screen. Ok, i did that. Well, now he want that when a user fills new fields the PNP is not read i.e GET PERNR shouldn't be launched, so i my program i write this :
if myfield is initial.
GET PERNR.
else.
PERFORM get_data.
endif.
But when i compile program i can't do that and i don't know how to make this and if it's possible.
Regards,

Hi tafkap,
1. u have created a z report and
   u are using PNP logical database.
2. u say,
, now he want that when a user fills new fields the PNP is not read i.e GET PERNR shouldn't be launched
suppose this is achieved, then how
are u going to fetch the data
and show the report ?
3. If u already have the logic for
   getting information from database and showing
   to the user,
   then do not use GET event.
(It is not compulsory in a ldb)
4. Instead use START-OF-SELECTION
   event
   and do the normal programming.
5. In such case,
   the selection screen (and ur extra field(s))
   will be displayed as usual
   and your own code will get triggered
   at start-of-selection.
I hope it helps.

What is a Selection Screen and how to make it ?

What is a Selection Screen and how to make it ? Please explain the process.
Best regards,

Selection Screen are used for the program reports. These allows you to input some values that are required to show the desired output.
for example : you want to show the list of sales orders between 1000 to 1999, you would write a select query as this (to make u understand better)
select vbeln from vbak into it_vbeln
             where vbeln GE 1000 " greater than or equal to
               and vbeln LE 1999. " less than or equal to
now if you wnat to do it dynamically, you need a selection screen
tables : vbak. " declaration
selection-screen : begin of block block1 with frame title text-003.
select-options : so_vbeln for vbak-vbeln. " selection range from __ to __
selection-screen : end of block block1.
now you can write the same select query as
select vbeln from vbak into it_vbeln
             where vbeln in so_vbeln.
Hope this is clear now

Hi Senthil,
As far as my knowledge is concerned AT Selection-Screen output and AT Selection-Screen wont work together.In this code you are trying to do the validation in AT Selection-Screen. Instead of that try doin your validations in Start-of-selection Event.
i,e., modify your code as follows:
PARAMETERS: p_werks LIKE marc-werks OBLIGATORY MEMORY ID WRK,
p_lgort LIKE mard-lgort OBLIGATORY,
p_rlgort LIKE mard-lgort OBLIGATORY.
PARAMETERS: p_boml TYPE c RADIOBUTTON GROUP mode user-command flag.
SELECTION-SCREEN: BEGIN OF BLOCK b1 WITH FRAME TITLE text-001.
PARAMETERS: p_aufnr LIKE aufk-aufnr MODIF ID cp2.
SELECTION-SCREEN: END OF BLOCK b1.
*SELECTION-SCREEN COMMENT 1(44) text-004 FOR FIELD p_cmpl.
PARAMETERS: p_cmpl TYPE c RADIOBUTTON GROUP mode.
SELECTION-SCREEN: BEGIN OF BLOCK b2 WITH FRAME TITLE text-002.
PARAMETERS: p_matnr type marc-matnr MODIF ID cp1,
p_verid type afpo-verid MODIF ID cp1,
p_labst type mard-labst MODIF ID cp1.
SELECTION-SCREEN: END OF BLOCK b2.
PARAMETERS: p_mstr TYPE c RADIOBUTTON GROUP mode.
AT SELECTION-SCREEN output.
LOOP AT SCREEN.
IF p_boml <> 'X' AND
screen-group1 = 'CP1'.
screen-active = '1'.
MODIFY SCREEN.
ENDIF.
IF p_cmpl <> 'X' AND
screen-group1 = 'CP2'.
screen-active = '1'.
MODIFY SCREEN.
ENDIF.
MODIFY SCREEN.
ENDLOOP.
START-OF-Selection.
Perform validation.
form validation.
IF p_boml EQ 'X'.
IF p_AUFNR EQ space.

ENDIF.
endif.

Selection Screen and Selection Button

Hi,
I have put in a screen this
SELECTION-SCREEN PUSHBUTTON /01(20) p_0031 USER-COMMAND _0031.
But It never enters 'at user-command' event !
What should i do ?

Hi Stephan
If you specify the USER-COMMAND addition, the pushbutton must be assigned a function code fcode. The function code fcode must be specified directly and can only contain a maximum of 20 characters.
Before you can work with the pushbutton, you must specify a TABLES statement to declare an interface work area for the structure SSCRFIELDS from the ABAP Dictionary.
If the user selects the pushbutton on the selection screen, the runtime environment triggers the event AT SELECTION-SCREEN and the function code fcode is transferred to the ucomm component in the interface work area sscrfields.

Selection screen and DP

Hi friends
          Can any one tell me which event triggers first and the order of event triggering when both selection screen and dialog program is used..Also tell me which event wont fire.
Regards
Suresh.A

Here is the Sequence.
1. First Load-of-Program event is triggred by default when you execute any report.
2. Inisilization.
3. At-selection Screen output.
4. At selection Screen.
5. Start-of-selection.
6. end-of-selection.
if you are calling screen in your report you will be doing so in Start-of-selection
then after start-of-selection.
              Process before output
              Process after input
             (if you add POH, and POV, these event will trigger when you press F1 or F4)
              End-of-selection.
Thanks & regards

Selection Screen and Output

Hi,
I am developing one report. My customer is requested me he needs Selection-screen and Output of the report both need in the same screen i.e upper part is selection screen below is the Output..
Is it possible?
If YES could you please help me..........?
Thank you advance.......

Hi Kishore,
It is possible create the upper block using selection-screen this will be screen 1.Then create the another block and use INCLUDE to include the upper block.Hope your query resolves.
An example to create selection-screen.
SELECTION-SCREEN BEGIN OF BLOCK SEL1 WITH FRAME TITLE TIT1.
PARAMETERS: CITYFR LIKE SPFLI-CITYFROM,
CITYTO LIKE SPFLI-CITYTO.
SELECTION-SCREEN END OF BLOCK SEL1.
SELECTION-SCREEN BEGIN OF SCREEN 500 AS WINDOW.
SELECTION-SCREEN INCLUDE BLOCKS SEL1.
SELECTION-SCREEN BEGIN OF BLOCK SEL2
WITH FRAME TITLE TIT2.
PARAMETERS: AIRPFR LIKE SPFLI-AIRPFROM,
AIRPTO LIKE SPFLI-AIRPTO.
SELECTION-SCREEN END OF BLOCK SEL2.
SELECTION-SCREEN END OF SCREEN 500.
We can use loop at screen to make it active or inactive at user command.That is enter or F8 whatever user chooses.
Have a best day ahead.
