ALV Grid Problem - User command Back Cancel Exit

Hi Guys,
             I was trying to use the ALV grid and my problem is, on the grid display, when i try to hit the back button or exit or cancel, then a blank screen appears and i need to hit either back or other buttons one more time to go back to the selection screen.
             Is there any thing I am missing here? Please suggest me the solution.
Thanks in advance,
Srinivas.

hi srinivas,
we have 2 options in this case.
1) i think ur using EVENTS_GET function module. If u use sometimes we are facing this kind of problem. i think accroding to my knowliege its bug in SAP....
2) See in debug mode what is the user command for this back button everty time USERCOMMAND FOR BACK BUTTON not 'BACK' .If it ios correct plaese add the code for back button in user command event.
if u dont want to face that problem remove that events_get fm and write the code manually. i am not sure abt ur code.
i hope u got the point what i am saying.
Thanks,
Maheedhar

  • In Editable ALV the BACK/CANCEL/EXIT buttons are not working?

    Hello,
    I wrote a editable FM based ALV, working fine that when user changes the data and press SAVE button, values are transfering into prog. But, i need to put a validation that, if user changes the values and press BACK/CANCEL/EXIT button, i need to popup the message that "Do you want to save changes", my PF-STATUS is good(because, SAVE is working).
    But, its not working that when user done changes and press BACK button (forgot to press SAVE button), system taking me to selection screen/screen 0!! I my code is as below,
    FORM pick USING v_ucomm     TYPE syucomm
                                         it_selfield TYPE slis_selfield.
      DATA: v_answer TYPE char1.
      READ TABLE it_z_tbl  INDEX it_selfield-tabindex
       INTO w_z_tbl.
      CASE v_ucomm.
        WHEN '&IC1'.
            " working fine this functionality
          ELSE.
            MESSAGE i000 WITH 'Double click on key field'.
          ENDIF.
        WHEN 'SAVE'.
            " working fine this functionality
        WHEN BACK' " OR 'CANCEL' OR 'EXIT'.
          PERFORM popup_for_user_decision CHANGING v_answer.
          CHECK v_answer = '1'.
          PERFORM now_update.
      ENDCASE.
    ENDFORM.     
    when i put the break point on the first line of this piece of code, its not stopping on pressing BACK/CANCEL/EXIT buttons!! (its stoppig for SAVE press or double click)
    Its stopping at this point,
    CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'.
    EXPORTING
    i_callback_user_command  = 'PICK'
    IMPORTING
    EXCEPTIONS
    IF sy-subrc <> 0 =================> its stopping at this point!
    ENDIF.           
    Pls. let me know why system is not recognising that i hv a PICK form (SAVE and Double clicks are working fine)?
    Thank you

    Hi,
    Actually BACK is standard user command so it is not stopping and going to selection screen.
    Give some other use command like 'BCK' and try....

  • ALV GRID Problem with reading contents

    Hi there! I'm quite new with ABAP and I have some problems with the syntax of it. Maybe I should first describe my aim and then I'll show you my code.
    1. I read contents from two database tables, called 'zbc_dan_registry' and 'zbc_dan_category'.
    'zbc_dan_registry' has 2 columns: name, value.
    zbc_dan_category' has 1 column: category.
    Now I want to have an ALV Grid, that displays the contents of 'zbc_dan_registry' and one additional column with dropdown fields, where the user can select a category for each row. This is, what my code already does.
    Now I want to save the contents of the whole table in a new table 'zbc_dan_registrz' (you see: 'registrz', not 'registry'!) with 3 columns:
    name, category, value.
    My problem is, how can I read the contents of the ALV Grid, with the user selected category for each row, and save them in an internal table? I've tried to adapt the code of "BCALV_EDIT_04", but I don't get it running.
    Some detailled help would be great, you know, I'm really working hard to understand ABAP, but it's really hard for me. Thanks for your support and help!!

  • How to capture multiple rows of ALV grid when user selected?

    Actually,It is easy to get one single line.However, my user wants select several lines of ALV grid  by condition  .  i need to process the selected lines ,so i need to put these lines into an internal table. But now, i have no idea to capture the lines.
    What method for an ALV Grid will return the lines the user has selected?
    Appreciate for your help!

    Hi,
    Once user selects multiple rows and press another button for further execution, you can modify your internal table with marked rows using selection column.
    You need to add user command code in your ALV grid call. Please refer below code.
    CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
          EXPORTING
            I_CALLBACK_PROGRAM       = SY-REPID
            I_CALLBACK_PF_STATUS_SET = 'F_GUI_STATUS'
            I_CALLBACK_USER_COMMAND  = 'F_USERCOMMAND'
            I_GRID_TITLE             = TEXT-026
            IS_LAYOUT                = WA_LAYOUT
            IT_FIELDCAT              = I_FIELDCAT
          TABLES
            T_OUTTAB                 = I_OUTTAB

  • ALV GRID Problem when delete key is pressed from keyboard

    I have created a ALV Grid using cl_gui_alv_grid class
    I this I made one field editable based on some conditions
    and used SEL_MODE as 'A' ( i tried 'D' too) in the LAYOUT Settings
    When I select the records and press the DELETE key from keyboard
    the records are getting deleted, and i am not able to catch this action
    in the debug mode
    (FYI: I have written my own set of code for delete row in the USER COMMAND EVENT which is not getting triggered in this case )
    Can any body help me with this

    have you used this to trigger the event
    SET HANDLER W_EVENT_RECEIVER->HANDLE_USER_COMMAND FOR W_GRID

  • ALV Grid Problem in WebGUI

    Hi All,
    We've created an ALV grid using classes in R3 and we're testing it in WebGUI.  All of those scenarios are working fine in R3 however the behavior in WebGUI is different.  We're encountering a problem wherein the cellstyles are not being reflected (eg. a particular cell for a particular row should be grayed out if a particular field has this value).  Furthermore, if we enter a value in this field, it should automatically populate values for other fields (eg. column name - PERNR.  Once pernr is entered; column name - NAME should have a value automatically).  Another thing is, the Refresh button is  missing in WebGUI.  One more problem is that the error message for that particular column was not shown.  We're using the add_protocol_entry method, so it should generate a pop-up screen.
    Any solution for all these problems?  Are these problems limitations of the ALV Grid in WebGUI? 
    We'll appreciate all your responses.  Thanks a lot.

    Have a look at example code: BCALV_GRID_01, where they suppress the error by catching it...
    If you are using the ABAP Grid Control (OO object), you can still create the ALV list as a spool listing for the background job.
    The easiest way to do this is to put all the create object statements and method calls for the custom container and ALV grid object inside a subroutine (for example, present_grid).
    All that is required is a simple check of the sy-batch variable to determine if the program is being executed in the foreground or background.
    e.g. if sy-batch is initial.
    call screen 0100.
    else.
    perform present_grid.
    endif.
    In a PBO module of screen 0100, the subroutine present_grid is also performed.
    The set_table_for_first_display method will be invoked in the routine present_grid, however, due to the job being executed in the background, the ALV list output will be written as spool output for the background job.

  • Refresh alv grid after user clicks f4( value-request)

    Hello Experts,
    I am currently developing a module pool program wherein after the user selects a value via f4(value request),
    my ALV grid(using custom control) should be refreshed to show the new records selected based
    on the f4 value. How can this be achieved?
    thank you guys and take care!

    Did you try a CALL METHOD [cl_gui_cfw=>set_new_ok_code|http://help.sap.com/saphelp_sm32/helpdata/en/06/3fa1b79f2811d2bd68080009b4534c/frameset.htm] and [=>flush|http://help.sap.com/saphelp_sm32/helpdata/EN/06/3fa1879f2811d2bd68080009b4534c/content.htm] in the POV section or in event onF4 handler method to force execution of PAI (either it works either it dumps)

  • How to show an ALV grid in planning book (using macro-exit)

    Hi Expertss,
    I am using a macro-exit. Now in the execution flow of this macro-exit I am required to shaow an ALV grid. I tried calling a Zreport in which i am calling alv screen(screen type dialog box). It is giving a short-dump saying Exception condition "CNTL_ERROR" raised.
    If i comments the fieldcatlog and structure name while calling the ALV in my Zreport then the alv is coming but then planning book is not vivible.
    Kindly tell what thing I am missing and what probable thing I can do to make it work.
    Thanks a lot in advance.

  • Alv grid problem

    Hi,

    Will u tell me what is the problem here. I wanted to when i press f3 it will display my selection screen.
    Plz give me proper solution.

    Hi,
    This occurs because your output for alv is printed twice.
    1st with the header and then with the item.
    Try to print the whole at the same time.

  • ITS 6.20 patch 18 ALV Grid problems

    Hi,
    We are in the midst of testing the ITS 6.20 patch 18 with EP6 SP12 and we have run into some problems that were not evident with 6.10. 
    First.  With IAC PP_MY_REQUIREMENTS (Requirements Profile) and PP_MY_PROFILEMATCHUP (Profile Matchup), there is now a visible horizontal bar that goes across the whole window.  It can be moved up and down.  This is not there in 6.10.
    Second.  With the new PZ31_EWT (Edit Qualifications) transaction, when you select a qualification on the left and it then appears on the right, the dropdown for the ALV grid does not stay droped down when clicked.  You have to hold the mouse button, and then when you drag over top of the choice that you want, it doesn't select it, BUT, if you use your arrow keys on the keyboard, it changes the value.
    Third.  With PV8I (Internal Training), when viewing the Booking Information in the bottom of the screen, the top line/header of the window is only 1/8 visible.
    Has anyone run into any of these problems before?  Does patch 19 or 20 (when it comes out) solve any of these problems?
    Sorry for all the ranting!!
    Cheers,
    Kevin

    May be try this in ITS forum for a better response.

  • ALV Grid: Problem with errors

    Hi,
      Many of you must have definitely experienced this problem.
    I have some default rows on ALV screen for user to enter data.
    Say field1, field2 are in the fields list. Now if user puts values in field2, I consider that as a change and I validate entire row. Say field1 is mandatory. I show an error on field1 when field2 has been changed by adding protocol entry.
    Now if user changes different row and presses enter, mod_cells does not contain entries related to field1 for first row even though protocol contains errors for field1 on first row. Because of this, first row is not getting validated again.
    I added adding an entry in mod_cells for field1. It does not seem to work.
    Please let me know if you have any solution for this problem.
    Thanks.
    Srinivas.

    Hi Aaron,
    set_selected_cells or so is the method. then user is positioned at the error cell.
    regards,

  • SAPGUI for JAVA 7.00 rev 5 - ALV grid problem

    Hello all,
    I've created simple program using editable ALV grid to edit custom database table in the dictionary.
    After upgrading to rev 5 I can't delete any row from the grid. After clicking the minus sign on the grid toolbar nothing happens. In the release note for the rev. 5 is written that protected rows can be no longer deleted. But I haven't written any code to protect any row in the grid.
    When run on SAPGUI 7.00 rev 4 or SAPGUI for windows 7.10 it works.
    Thanks for any help.

    Hello Petr,
    both in "BCALV_GRID_EDIT" and in "BCALV_GRID_VERIFY" which we use as testreports for editable ALV grid, I can select a line and delete it using the the "delete line" icon in the grid's toolbar running SAP GUI for Java 7.00 rev 5.
    Can you somehow reproduce the issue with the mentioned reports (playing with the options)?
    Otherwise we would need access to your custom program. Then it would be helpful if you could <a href="http://service.sap.com/message">create a message</a> on component BC-FES-JAV and make your system available to us.
    Best regards

    Maybe not the most elegant way to do this but here is an solution to skip the message "Subsequent documents exist":
