Hi friends,

set_table_for_first_display using display interactive reports.

My task: When am i select Some row in First Display and Execut My Second display have same related records data.

I have idea how to do Using Function Modules. I should use Class&Methods.

Please give idea about that.

Hi Thrimu,

This is achievable. What you have to do is to make the relevant field of the first ALV as hotspot. Then you should create an event handler class to handle the HOTSPOT_CLICK event of CL_GUI_ALV_GRID. In that class you have to create a method to handle this event. Within this method you will be getting the Row ID, Column ID & Row No. that you select. Based on this you will be able to select the related data for your second ALV. Then display this by calling another screen.

Please have a look at the following SCN contants:

Hi Thrimu,

You have to trap the events using Event Handler Class and binding the event double click to the same for the ALV for showing the result on the next display.

Pl refer following code as a reference:

Hope this helps.

Hi Thrimu,

Ok. So what you want is to show related data to all the records selected on the first ALV. In this case, you need to create an additional button on the ALV toolbar using the event handler class. After you select multiple records, you can click on this button to show th second ALV.

Declare your event handler class as follows:

CLASS lcl_alv1_handler DEFINITION.

   PUBLIC SECTION.

     "To handle adding buttons to toolbar

     METHODS handle_toolbar_set FOR EVENT toolbar OF cl_gui_alv_grid

               IMPORTING e_object e_interactive.

     "To handle button click of newly added buttons

     METHODS handle_user_command FOR EVENT user_command OF cl_gui_alv_grid

               IMPORTING e_ucomm.

ENDCLASS. 

CLASS lcl_alv1_handler IMPLEMENTATION.

     METHOD handle_toolbar_set.

          CLEAR wa_button.

          wa_button-function  = '&SHOW'.

          wa_button-icon      = '@10@'.

          wa_button-butn_type = '0'.

          wa_button-quickinfo = 'Second ALV'.

          APPEND wa_button TO e_object->mt_toolbar.

     ENDMETHOD.

     METHOD handle_user_command.

          CASE e_ucomm.

               WHEN '&SHOW'.

                    "Please make your selections here based on the selected records from the first

                    "ALV. The selected records can be identified based on CHECKBOX = 'x'.

                    "Then call your second ALV.

          ENDCASE.

     ENDMETHOD.

ENDCLASS. 

Then before you call the  set_table_for_first_display method of CL_GUI_ALV_GRID, you need create an object for the above event handler class and register the events. Can be done as follows.

CREATE OBJECT o_container1

       EXPORTING

         container_name              = 'CUSTCON1'

       EXCEPTIONS

         cntl_error                  = 1

         cntl_system_error           = 2

         create_error                = 3

         lifetime_error              = 4

         lifetime_dynpro_dynpro_link = 5

         OTHERS                      = 6.

     IF sy-subrc <> 0.

*     MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

*                WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

     ENDIF.

     CREATE OBJECT o_alv1

       EXPORTING

         i_parent          = o_container1

       EXCEPTIONS

         error_cntl_create = 1

         error_cntl_init   = 2

         error_cntl_link   = 3

         error_dp_create   = 4

         OTHERS            = 5.

     IF sy-subrc <> 0.

*     MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

*                WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

     ENDIF.

CREATE OBJECT o_alv1_handler.

SET HANDLER :  o_alv1_handler->handle_toolbar_set FOR o_alv1,

                          o_alv1_handler->handle_user_command FOR o_alv1.

CALL METHOD o_alv1->set_table_for_first_display

       EXPORTING

         is_layout                     = wa_layo

         it_toolbar_excluding          = gt_excl_toolbar

       CHANGING

         it_outtab                     = gt_final

         it_fieldcatalog               = gt_fcat

       EXCEPTIONS

         invalid_parameter_combination = 1

         program_error                 = 2

         too_many_lines                = 3

         OTHERS                        = 4.

     IF sy-subrc <> 0.

*     Implement suitable error handling here

     ENDIF.

I think you have got a basic idea on how this can be achieved. Please check & revert back.
