Double click on ALV Report using Module Pool Program

[Former Member]

Hi Friends,

               I am working on a module pool programming where i need to develop few screens based on radio buttons in initial screen .

                  rb1 - create

                  rb2- change

                  rb3 - Report

              if Report option is selected, report needs to be displayed, again double clicking on a field(eg, Material) in the report should call change screen based on material which was double clicked.

how should i achieve this please suggest.

regards,

I'd declare rb1, rb2 and rb3 as CHAR1 with values of space or 'X'. If possible, make them a radio group. If not, make them checkboxes and add logic that exactly one will be set. Then write this code:

case 'X'.

when rb1.

   " create logic

  when rb2.

   " change logic

when rb3.

   submit xyz ... and return. " or do you mean call the module in display mode?

endcase.

If you need to differentiate the mode, set a flag TRTYP (like SAP does). They use 'H' for create (hinzufügen), 'V' for change (verändern) and 'A' for display (anzeigen). In the PBO of a screen, loop at screen and set fields to no input in mode 'A'. I think it's SCREEN-OUTPUT = '0'. Don't forget to modify SCREEN inside the loop.

If very little information gets passed from the ALV, you may be better off to write a stand-alone module pool transaction and pass key values via SPA/GPA (set/get parameter).

thanks for ur reply,

Look at the callback routine (find an existing ALV for that). The user command is something like '%IC2' (not 100% sure). The callback gives you a parameter (structure) that has index information on the row and it also has information on the field. You may need to re-read the data table for the ALV using that index to get the proper line.

Code a 'WHEN' for that user command, put a breakpoint and have a look at the data. Click a few different fields and rows and you'll figure it out.

Hi,

    I am displaying ALV in a screen( PBO) in modulepool using custom container, Now how to capture the double click action on any row or a particular field. based on that i need to call another screen.

Please suggest

Check sy-ucomm for click/double click. See this thread

Hi,

Basically it is a Report that is displayed in PBO screen , Now what is the code i need to build in PAI while double clicking on a row or a field,

please eloberate.

[Former Member]

In you PAI, add a condition to check the action(sy-ucomm).

You can simply add

IF sy-ucomm = '&IC1'. "&IC1 is double click

     "your processing/logic here.

ENDIF.

Sorry,

IT did not worked,

I am working in modulepool and displaying report in one screen-PBO using custom container using cl_gui_alv_grid class , please consider all these things while providing solution.

code in PAI for double clicking report field.??

[Former Member]

ok. I got your point now. This sample program will surely solve your issue:

BCALV_GRID_05

Note: Update the Logic on this part for double click:

(Use the '&IC1' in sy-ucomm to check for double click.

METHOD handle_user_command.

     DATA: lt_rows TYPE lvc_t_row.

     CASE e_ucomm.

       WHEN 'BOOKINGS'.

         CALL METHOD grid1->get_selected_rows

                  IMPORTING et_index_rows = lt_rows.

         CALL METHOD cl_gui_cfw=>flush.

         IF sy-subrc ne 0.

* add your handling, for example

           CALL FUNCTION 'POPUP_TO_INFORM'

                EXPORTING

                     titel = g_repid

                     txt2  = sy-subrc

                     txt1  = 'Error in Flush'(500).

         else.

                   perform show_booking_table tables lt_rows.

         ENDIF.

     ENDCASE.

   ENDMETHOD.                           "handle_user_command
