ALV with objects

Former Member — Wed, 05 Sep 2007 14:12:51 GMT

Hi , I am new to the concept of ALV with OOP ,

I have built an internal table to be displayed , it is required that it need to be editable at the report screen , so I will have to use oops . I have been going through the sflight examples , Since I have my own internal table what should I pass in i_structure_name = ' ' , and if there is a simple source code to help me better understand this concept , i will really appreciate it.

thank you

Hi Krish,

You need to follow these simple steps.

1). Define a screen in your program and using se51 just place a custom container object on the screen and drag it to size of the ALV display you need.

2). use the code below in your PBO module

MODULE status_0901 OUTPUT.

  SET PF-STATUS c_zvxxstatus.     <=== what ever menu you need

  SET TITLEBAR  c_zvxxtitle.          <=== what ever title you need 

  CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
    EXPORTING
      i_structure_name       = c_zsxx_zrpo_struc     <=== Structure of your internal table
      i_client_never_display = c_x
    CHANGING
      ct_fieldcat            = i_fieldcat_lvc[]
    EXCEPTIONS
      inconsistent_interface = 1
      program_error          = 2
      OTHERS                 = 3.

  IF sy-subrc NE 0.

    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

  ENDIF.


IF ob_custom_container IS INITIAL.

    CREATE OBJECT ob_custom_container
           EXPORTING
              container_name = c_container.

    CREATE OBJECT ob_grid
           EXPORTING
             i_parent = ob_custom_container.

* make the rows zebra pattern and optimize the width of the colum
    MOVE c_x TO e_layout-zebra.

    MOVE c_x TO e_layout-cwidth_opt.

* set table for first display
    CALL METHOD ob_grid->set_table_for_first_display
      EXPORTING
*        i_structure_name = c_zsxx_zrpo_struc
        is_layout        = e_layout
      CHANGING
        it_outtab        = t_orders[]
        it_fieldcatalog  = i_fieldcat_lvc
        it_sort          = t_sort[].

  ENDIF.

3). In the PAI module create a routine to handle the actions on the screen and menus


MODULE user_command_0901 INPUT.

*  actions according to the function code of the buttons
  MOVE w_ok_code TO w_save_ok.

  CLEAR w_ok_code.

  CASE w_save_ok.

    WHEN c_exit OR c_cancel OR c_back.

      PERFORM f_do_exit.

    WHEN OTHERS.

*     do nothing
  ENDCASE.

ENDMODULE.

Check the code above its pretty simple to get a alv output using OOPS

Hope this helps

Cheers

Hi.

You can use cl_salv_table for display data. https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/5dc3e690-0201-0010-1ebf-b85b3bed962d

but, If you need set editable alv use CL_GUI_ALV_GRID: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/4544e790-0201-0010-c29c-e46c389f5a96

In the fieldcat use edit = 'X' to set it editable.

    CLEAR wa_fieldcat.
    wa_fieldcat-fieldname = 'DATE'. 
    wa_fieldcat-col_pos =  1.           
    wa_fieldcat-decimals_o = 0.
    wa_fieldcat-datatype = 'DATS'.
    wa_fieldcat-no_zero   = 'X'.
    wa_fieldcat-edit    =  'X'. 
    wa_fieldcat-outputlen = 8.
    APPEND wa_fieldcat TO gt_fieldcat.
