What is AT Exit-Command in MPP

Hi all
What is AT Exit-Command in MPP...

Hi rohini,
The statement associated with at exit command is :
MODULE <module_name> AT EXIT-COMMAND.
Addition AT EXIT-COMMAND at the event PAI causes module <module_name> to be called exactly as if:
a)The function used to trigger event PAI has function type "E"
b )Into the input field of the standard toolbar, the user entered a character string starting with "E" and confirmed it using ENTER.
The dialog module is called before the automatic input checks defined in the system or in the ABAP Dictionary and independent of its position in the event block. The only screen field transported to the ABAP program is the OK field. If the function that triggered the PAI event does not fulfill any of the above prerequisites, the MODULE statement is not executed.
If several MODULE statements have the AT EXIT COMMAND addition, only the first one is executed. If no MODULE statement has the addition AT EXIT COMMAND, a normal PAI processing is executed: The predefined input checks are executed and then the PAI event block is processed sequentially. Provided the screen processing is not terminated in the dialog module mod, after the return from the dialog module, the complete PAI processing is executed. You must not use the addition AT EXIT COMMAND in connection with the statement FIELD.
The function type of a function is determined in the Screen Painter or Menu Painter. Usually those functions of the user interface are defined with function type "E" that are assigned to the icons Back, Exit and Cancel in the standard toolbar of the GUI status. Therefore, the called dialog module should terminate the screen processing and allow security checks, if required.
If you are talking about the on exit-command in report programming,
then the statement associated with it is
at selection-screen on exit-command.
Effect
This event is triggered if the user has called one of the functions Back, Exit or Cancel. In the event block, possible clean-up actions can be executed.

Table T063O and the PAI delcare "MODULE paimodule AT EXIT-COMMAND.

I have never declared a PAI module with the addition AT EXIT-COMMAND .
And I never hope to have to do so.
But if you want EXIT_SAPLIE01_007 to fire in MB02 like it fires in MIGO, you're gonna have to learn all about the "AT EXIT-COMMAND addition".
And then, you're gonna have to learn about table T063O.
And then, you're gonna have to try and remember who your IM configurator was or is.
Reminds me of the old old big blue joke:
"It's 10pm - do you know where your JCL is?".
Anyway, do you think the "AT EXIT-COMMAND addition to PAI module declares is worth a blog? If so, then I've got two blogs stored up that I can post in the future, because Gareth has already said that the *tablename blog is worth posting.

Hi Rich -
Yes - that's why I gave the flow of control through the various modules.
You can't get to the user exit call in the lowest module UNLESS you type in a character string starting with "E" in the tcode/fcode box at the top of the screen (it doesn't have to be just an "E" - it can be any character string starting with E.)
But note that the reason for T063O is to place a little more security on this process in the case of the various MB02 screens that have this feature. The "E-initial" string that you type in to the tcode/fcode box has to be "pre-registered" in T063O - otherwise you get a message saying "Function Exxx not supported here" (this is done by the second module down in the flow of control.)
I can see why SAP did this - if it didn't have some control at the config level, then any consultant could "backdoor" an exit into MBO2 or MB03 and take home some really private data. I also suspect this is why you can't maintain T063O in SM30 - it's probably a config function - I haven't ascertained this yet for sure.
Finally, the only reason I happened to discover what SAP was up to here is because I couldn't figure out why the same exit that's been working fine in MIGO didn't work at all in MB02 - it wasn't even called. And to figure this out I had to trace the flow of control backwards until I discovered the "E-string" logic and the "T0630" pre-registration logic in the top two PAI modules.
So that's why SAP's use of this feature was a big surprise to me too - I also have never seen it and I've studied a fair amount of SAP standard code looking for exits and BADI interrupts.

MODULE USER_COMMAND_0200 AT EXIT-COMMAND.

Hi Experts,
I knew that the following statements allows user to by pass all the screen validations, so to achieve this we have to declare a function code in SET PF-STATUS of type Exit Command. So, my doubts r,
1- Anyway, we r adding the AT EXIT-COMMAND as a suffix to to Module statement, so again What is the necessity declaring in the SET PF-STATUS as a function code?
PROCESS AFTER INPUT.
MODULE USER_COMMAND_0200 AT EXIT-COMMAND.
2- What else wuld do the above statement apart from overcoming the validations(coz the author has mentioned this statement - ''An Exit-command allows you to insert functionality into the PAI that by passes all screen validation '', Which is I dont understand!)?
ThanQ.

hi Srinivas,
Let us consider the following example:
If a user wants to exit a screen, by clicking the BACK button, he should be taken out ..right?
Instead, should there be a message poping up saying "Mandatory fields are not entered".. or "enter character data in name field"...ect..?
no...hence, to ignore these validation, we put the code to exit the screen in a module. This module has to be defined with ...AT EXIT-COMMAND extension.
Hope this answers your question.

At selection-screen on exit-command

hi to all my querry is as follows . pls tell what is the usse of
at selection-screen on exit-command event where do we use it . can u pls give some sample coding . points will be rewarded definitely .

Hi
We use<b> exit-command </b> in Module pool programs to come out of the Program, without entering data in the madatory fields on screen.
We don't use exit commands for selection screens in Reports
So you are asking this exit command for selection screens
see the sample code for Module pools programs
PROCESS AFTER INPUT.
Forced Exit from the transaction
MODULE exit AT EXIT-COMMAND.
*&      Module exit INPUT
Exit from the Transaction
MODULE exit INPUT.
CASE okcode.
    WHEN 'EXIT' OR 'CANCEL'.
      CLEAR okcode.
      LEAVE PROGRAM.
ENDCASE.
ENDMODULE.                 " exit INPUT

Module at-exit command

Hi,
Inside this module I have logic for ok_code
WHEN 'EXIT'.
perform pop_up.
form pop_up.
function module: do you want to save the changes?
if yes.
" perform save_changes.
" leave program
for msave_changes.
perform incompletion_logic.
" save changes
endform.
when iam doing this I have error messages for incompletion inside the incompletion_logic routine.
and when i issue an error message
iam getting short dump saying 'error message inside module atexit command' invalid dynpro state'.
what is the correct process to do this.
Thanks

Like the system message, you cannot throw a error message inside the AT_EXIT module.
You can call that module, in the PAI (Not at AT-EXIT command) and call the popup and do the required validations.

Ravi

AT EXIT-COMMAND in ABAP OO

Hi everyone!
I need to execute some instructions when user exit from the program.
Something like AT EXIT-COMMAND in PAI.
But i dont have any PAI module or declared flow logic in my screen definition,
becouse screen is calling automaticly by abap, i cant change anything there.
Structure of my program is similiar to this: [http://help-abap.blogspot.com/2008/10/dispaly-alv-report-output-in-same.html|http://help-abap.blogspot.com/2008/10/dispaly-alv-report-output-in-same.html]
How i should run some code when user leave the program?
EDIT:
ok, i got solved it
i needed this one:
AT SELECTION-SCREEN ON EXIT-COMMAND .
PERFORM EXIT_PRG.
Best regards,

EXIT command behaviour in ABAP code?

Hi Experts,
Pls. let me clarify that, the behaviour of EXIT command, like,
- in IF statement
- in LOOP
- in PERFORM/FORM
-in DO
thanq

to exit out of the event blocks and the loops we will use exit command.
see these links for more info.
http://help.sap.com/saphelp_nw70/helpdata/en/9f/db9af135c111d1829f0000e829fbfe/content.htm
terminating the loop using exit
DO 10 TIMES.
IF sy-index = 3.
EXIT.
ENDIF.
WRITE sy-index.
ENDDO.
The list output is:
1 2
module exit input.
if ok_code = 'REFR'.
call transaction 'ZMEDEMP'.
elseif ok_code = 'BACK'.
set screen 0.
leave to screen 0.
elseif ok_code = 'EXIT'.
leave program.
endif.
endmodule.
For E.g
AT EXIT-COMMAND code.
In your flow logic, you create a module as so:
MODULE md_exit_command AT EXIT-COMMAND.
Then in PF-status, you configure the Cancel (red button on toolbar) as exit button by setting Type of button as 'E'. Put OKCODE as 'CANC'.
Then, in the module
MODULE md_xit_command INPUT.
CASE OKCODE.
WHEN 'CANC'. LEAVE TO SCREEN 0. ENDCASE.
ENDMODULE.

Is it possible to add the exit command to a button in ALV OO toolbar

Hi ABAP folks,
is there are a way to add the exit command to a button of an ALV toolbar (like in the GUI status)?
I want to prevent the field validations of a dynpro field at PAI.
Thanks and regards,
Martin

Manage the event [TOOLBAR|http://help.sap.com/saphelp_erp2004/helpdata/en/ee/c8e07dd52611d2b468006094192fe3/frameset.htm] of CL_GUI_ALV_GRID.
This event is triggered by the ALV each time the toolbar of the control needs to be regenerated. To add self-defined functions to the toolbar, you trigger the event using method set_toolbar_interactive and write an event handler method ( see also: Defining GUI Elements in the Toolbar).
Look at demo BCALV_GRID_05.

Module exit at exit-command

Hi all,
    While I am using MODULE EXIT AT EXIT-COMMAND
its not working properly in module pool in PAI for the main screen.
code tht i m using for it is as follows.
DATA : l_ans TYPE c.
CLEAR ok_code.
*ok_code = sy-ucomm.
CASE ok_code.
   WHEN 'BACK' OR 'CANCEL' OR 'EXIT'.
      CALL FUNCTION 'POPUP_TO_CONFIRM'
        EXPORTING
          text_question = 'Would you like to Quit ?'(004)
          text_button_1 = 'Yes'(005)
          text_button_2 = 'No'(006)
        IMPORTING
          answer         = l_ans
        EXCEPTIONS
          text_not_found = 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.
      CHECK l_ans = '1'.
      LEAVE PROGRAM.

Hello Amit,
Please check whether you have assigned Exit Command Type to your buttons or not; in order to do that, go to the specific screen->PF-Status->Choose any standard button(you have assigned)->double-click->Set FUNCTIONAL TYPE.
E Exit Command (MODULE xxx AT EXIT-COMMAND)
S System Function
T Call a Transaction
   Normal Application Function
P Local GUI Functions
H Internal Use
Moreover, Module set for this exit-command with screen, should be;
In PAI;
MODULE exit_scr100 AT EXIT-COMMAND.
MODULE exit_scr100 INPUT.
CASE ok_code.
    WHEN 'CANCEL'.
      LEAVE TO SCREEN 0.
    WHEN 'EXIT'.
      LEAVE PROGRAM.
ENDCASE.                                " CASE OK_CODE
ENDMODULE.
We use AT EXIT-COMMAND, when we want to cancel out the screen or exit the screen, despite errors. Otherwise, screen would hang-up asking for correcting errors.
Hope it helps you,
Zahack.

MODULE AT EXIT-COMMAND not triggered

Hi,
I have placed module USER_COMMAND_9000 at exit-command in PAI but it will never be called whenever I click on button Entr, Back, Exit and Canc. I have activated the interface and everything else, also set the function key. Below is my code.
PROCESS BEFORE OUTPUT.
MODULE STATUS_9000.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_9000 AT EXIT-COMMAND.
MODULE STATUS_9000 OUTPUT.
SET PF-STATUS 'STATUS_9000'.
SET TITLEBAR 'TITLE_9000'.
ENDMODULE.                 " STATUS_9000 OUTPUT
MODULE USER_COMMAND_9000 INPUT.
CASE sy-ucomm.
    WHEN 'ENTR'.
      PERFORM populate_output.
    WHEN 'BACK'.

    WHEN 'CANC'.
      LEAVE TO SCREEN 0.
ENDCASE.
ENDMODULE.                 " USER_COMMAND_9000 INPUT

Hi,
Do the following.
In the screen flow logic.
PROCESS BEFORE OUTPUT.
MODULE STATUS_1000.
PROCESS AFTER INPUT.
MODULE exit AT EXIT-COMMAND.
MODULE USER_COMMAND_1000.
Now in F01,
MODULE exit INPUT.
CASE sy-ucomm.
     WHEN 'ENTR'.
       PERFORM populate_output.
     WHEN 'BACK'.
       LEAVE TO SCREEN 0.
     WHEN 'EXIT'.
       LEAVE PROGRAM.
     WHEN 'CANC'.
       LEAVE TO SCREEN 0.
ENDCASE.
endmodule.                 " exit INPUT

To perform database update in a module with AT EXIT-COMMAND addition

Dear All,
I have a function code 'EXIT' with function type 'E'. When this function code is triggered, my screen should close.
In the module that handles this function code (defined with AT EXIT-COMMAND addition), I will prompt the user whether he/she want's to save the data before exiting with the POPUP_TO_CONFIRM_STEP function module. The text message in the dialog box is "Do you want to save before exiting?".
When the user wants to save the data, a simple UPDATE statement will be executed to write the data on screen to database.
The problem here is since the module is defined with AT EXIT-COMMAND addition, the data on screen won't be copied to their corresponding variable on the code (correct me if I'm wrong). Therefore, even though database update is performed, the data written to database are no different that the original.
How to perform database update in a module with AT EXIT-COMMAND addition?
or
Is it even a "custom" or a "good practice" to prompt user to save data before exiting?
Thanks in advance,
Haris

With an exit command, if there's anything that would be lost, I would prompt "Data will be lost, do you wish to continue?". If they do, the database is not updated, if they don't, they stay in the transaction.
This is because the exit command runs before validation. So how can you know the data is correct?
If you have a button to leave the transaction that isn't an exit command, then you could prompt to save instead. There the choices should be - quit without saving, save and quit, don't quit.
Doing a database update in an exit command is not a good idea.

      set screen 0.
      leave screen.
endcase.
endmodule.                 " cancel INPUT
thanq

hi check this...
Calling a Module for Type E Function Codes
When the user chooses a function with type E, the screen flow logic jumps directly to the following statement:
MODULE mod AT EXIT-COMMAND.
Regardless of where it occurs in the screen flow logic, this statement is executed immediately, and before the automatic checks for the field contents on the screen. Before the module mod is executed, only the contents of the OK code field are transported to the ABAP field with the same name. However, no other screen fields are transported. If you have more than one MODULE statement with the AT EXIT-COMMANDaddition, only the first is executed. If there are no MODULE statements with the AT EXIT-COMMAND statement, normal PAI processing resumes.
If the user chooses a function whose function code does not have type E, the MODULE <mod> AT EXIT-COMMAND statement is not executed.

venkat.
