Screen programming and ALV

Former Member — Wed, 05 Aug 2009 03:31:05 GMT

Hi,

I have screen 9000 which consists of a few input fields. Once entered, in PAI, it will PERFORM print_report which will return an ALV report ( CL_SALV_TABLE ). When I click 'BACK' from the ALV, it will process the PBO of standard program SAPLSLVC_FULLSCREEN which will bring me back to the screen before 9000. How do I force it not to load to this standard program PBO but to take my own coded MODULE USER_STATUS_9000? What I need is, to go back to screen 9000.

Hi,

Please set the PF status BACK button and write the logic in the PAI event.

case:

when 'BACK':

call your perform statment.

endcase.

I think the above method will help you.

Regards

Sunil

Do you mean I only show my ALV report upon clicking BACK? That's not what I want. I need to show the ALV right after user enter info on screen 9000.

no u can call your alv on the click of F8 or execute on screen 9000 but u have to set the back button on the screen on which alv is displaying. In case of more clarification paste your code .

Thanks,

Hi,

Create a PF status including a back button.

As you are using the class CL_SALV_TABLE, by using the method SET_SCREEN_STATUS of this class you can set the PF status for your alv display.

create an object for handling the events.

Implement the class for handling user commands.

See the below code snippet. i may help you.

it_table->set_screen_status(
          pfstatus      =  'PF_STATUS'
          report        =  sy-repid
          set_functions = it_table->c_functions_all ).

*     Events for navigation through hotspot
        DATA: o_event TYPE REF TO cl_salv_events_table.

o_event = it_table->get_event( ).

        CREATE OBJECT o_events.

*     Register to the event USER_COMMAND
        SET HANDLER o_events->on_user_command FOR o_event.
