Double clicking on ALV in order to display a detail screen

Posted on Feb 14, 2018 at 07:14 PM 602 Views Last edit Feb 14, 2018 at 07:15 PM 2 rev.

Hi all,

When working with SE16, I can bring up a detail screen by just double-clicking one of the ALV’s lines. Similarly, when displaying an ALV from my own, a detail screen can be shown by either clicking the corresponding icon or by pressing CTRL+SHIFT+F3.

What I would like to know is how to display the detail screen in my (Z) program by just double clicking a particular line.

Thanks in advance,

Luis

    hi

    for your requirement pass function code of details screen to attribute of layout in alv.

    for info, please see below simple code.

    REPORT ZDEMO2.

    TYPE-POOLS:SLIS.

    TYPES:BEGIN OF TY_FINAL,
    VBELN TYPE VBAK-VBELN,
    KUNNR TYPE VBAK-KUNNR,
    END OF TY_FINAL,
    TT_FINAL TYPE STANDARD TABLE OF TY_FINAL.


    DATA:GT_FINAL TYPE TT_FINAL,
    GS_FINAL TYPE TY_FINAL.


    DATA:GS_LAYOUT TYPE SLIS_LAYOUT_ALV.

    DATA:GT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,
    GS_FIELDCAT TYPE SLIS_FIELDCAT_ALV.







    START-OF-SELECTION.

    SELECT VBELN KUNNR FROM VBAK INTO TABLE GT_FINAL UP TO 700 ROWS.





    END-OF-SELECTION.



    CLEAR GS_FIELDCAT.
    GS_FIELDCAT-FIELDNAME = 'VBELN'.
    GS_FIELDCAT-SELTEXT_L = 'SO Number'.
    APPEND GS_FIELDCAT TO GT_FIELDCAT.

    CLEAR GS_FIELDCAT.
    GS_FIELDCAT-FIELDNAME = 'KUNNR'.
    GS_FIELDCAT-SELTEXT_L = 'Customer Code'.
    APPEND GS_FIELDCAT TO GT_FIELDCAT.


    CLEAR GS_LAYOUT.
    GS_LAYOUT-F2CODE = '&ETA'. " note here pass function code of details to layout attribute.



    CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
    I_CALLBACK_PROGRAM = SY-CPROG
    IS_LAYOUT = GS_LAYOUT
    IT_FIELDCAT = GT_FIELDCAT
    TABLES
    T_OUTTAB = GT_FINAL
    EXCEPTIONS
    PROGRAM_ERROR = 1
    OTHERS = 2.

    IF 1 = 4.

    ENDIF.

      hi

      for FM REUSE_ALV_GRID_DISPLAY_LVC please see below sample report.

      REPORT ZDEMO2.



      TYPE-POOLS:SLIS.

      TYPES:BEGIN OF TY_FINAL,
      VBELN TYPE VBAK-VBELN,
      KUNNR TYPE VBAK-KUNNR,
      END OF TY_FINAL,
      TT_FINAL TYPE STANDARD TABLE OF TY_FINAL.

      GS_FINAL TYPE TY_FINAL.


      DATA:GS_LAYOUT TYPE LVC_S_LAYO.

      DATA:GT_FIELDCAT TYPE LVC_T_FCAT,
      GS_FIELDCAT TYPE LVC_S_FCAT.








      START-OF-SELECTION.

      SELECT VBELN KUNNR FROM VBAK INTO TABLE GT_FINAL UP TO 10 ROWS.





      END-OF-SELECTION.



      CLEAR GS_FIELDCAT.
      GS_FIELDCAT-FIELDNAME = 'VBELN'.
      GS_FIELDCAT-SCRTEXT_L = 'SO NUMBER'.
      APPEND GS_FIELDCAT TO GT_FIELDCAT.

      CLEAR GS_FIELDCAT.
      GS_FIELDCAT-FIELDNAME = 'KUNNR'.
      GS_FIELDCAT-SCRTEXT_L = 'Customer Code'.
      APPEND GS_FIELDCAT TO GT_FIELDCAT.





      CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
      EXPORTING
      I_CALLBACK_PROGRAM = SY-CPROG
      I_CALLBACK_USER_COMMAND = 'USER_COMMAND'
      IS_LAYOUT_LVC = GS_LAYOUT
      IT_FIELDCAT_LVC = GT_FIELDCAT
      TABLES
      T_OUTTAB = GT_FINAL
      EXCEPTIONS
      PROGRAM_ERROR = 1
      OTHERS = 2.



      IF 1 = 4.

      ENDIF.



      ************************


      FORM USER_COMMAND USING R_UCOMM LIKE SY-UCOMM
      RS_SELFIELD TYPE SLIS_SELFIELD.

      IF R_UCOMM = '&IC1'.
      R_UCOMM = '&ETA'.
      ENDIF.


      ENDFORM.

      here you have to use user_command Exit form.

    Hi Luis,

    If you are using CL_GUI_ALV_GRID in your custom program, the following are the steps to achieve it:

    1. Register event handler method for double click, then this method is called for every double-click on particular line
    2. In the event handler method, read the line using row id/index, and prepare details to be displayed
    3. Finally, make a call to LVC_ITEM_DETAIL (FM) to display details

    =

    Regards,
    Balaji

      Balaji,

      Thanks for your answer.

      I'm aware of both, handling events for double-click and the LVC_ITEM_DETAIL FM. Nevertheless, I thought that *maybe* there was a simpler or more direct method in ABAP. After all, somehow the ALV is able to do it behind the scenes and I hoped that there was a way to "intercept" or call this method directly, without any need to identify and isolate the record, copy it to another itab, etc.

      Thanks again,

      Luis
