Hi Łukasz,
I tried to understand and do myself, but sorry without result.

I used FALV for a fast ALV popup, just for showing some data result..... the question is about the GREEN OK button....

If the user click on it.... nothing happens.

Maybe I miss something....... there is a way to hide it, and keep only the second "X" button that just close the popup?

One point is also... that this popup is encapsulated into static method that I can call from everywhere, also BADI implementation.

So I cannot manage easly the usual event manager of a custom report.

Hi Roberto,
As far as I remember you'll need to redefine the event handler for the evf_user_command. I'm sure it should be shown somewhere in the demo program Zdemo_falv13. I'll check tomorrow as I'm on the road today.
I'll cover back to you.
Cheers
Łukasz

could be also that there is no solution.....

as I said I am into a custom class inside a static method that can sho this popup...... method that can be called from everywhere.

this isn't really important... it is a nice to have.

Hi @RTagliento,

I could think of the following class. I need to change e_ucomm = CONTINUE to 'EXIT', before calling super->evf_user_command.

CLASS zcl_falv_popup DEFINITION
  PUBLIC
  INHERITING FROM zcl_falv
  FINAL
  CREATE PUBLIC .

  PUBLIC SECTION.

    CLASS-METHODS show_falv_popup

        VALUE(iv_end_column)   TYPE i OPTIONAL
        VALUE(title_v1)        TYPE string OPTIONAL
      CHANGING
        ct_table               TYPE STANDARD TABLE

        VALUE(e_ucomm)         TYPE sy-ucomm .
  PROTECTED SECTION.

    METHODS evf_user_command REDEFINITION.
  PRIVATE SECTION.

    DATA ucomm TYPE sy-ucomm .
ENDCLASS.

CLASS ZCL_FALV_POPUP IMPLEMENTATION.
  METHOD evf_user_command.
    CASE e_ucomm.
      WHEN 'CONTINUE'.
        ucomm = 'CONTINUE'.
        e_ucomm = 'EXIT'.
        super->evf_user_command( e_ucomm ).
      WHEN 'CANCEL'.
        ucomm = e_ucomm.
        super->evf_user_command( e_ucomm ).
    ENDCASE.
  ENDMETHOD.

  METHOD show_falv_popup.

    "FALV creation with only table passed
    DATA falv TYPE REF TO zcl_falv_popup.
    falv ?= zcl_falv_popup=>create(
          EXPORTING i_popup = abap_true
                    i_subclass = cl_abap_classdescr=>describe_by_name( p_name = 'ZCL_FALV_POPUP' )

    falv->show_top_of_page( ).
    "Add title variable
    falv->title_v1 = title_v1.

          iv_start_column = iv_start_column
          iv_end_row      = iv_end_row
          iv_end_column   = iv_end_column
      ).
    ELSE.
      "Display popup with default size
      falv->display( ).
    ENDIF.

    e_ucomm = falv->ucomm.

  ENDMETHOD.
ENDCLASS.


REPORT zdemo_falv14.

      CHANGING
        ct_table        = sflight ).
  ENDIF.

  WRITE : / e_ucomm.

Thanks..... right.. I followed your suggestion.

I created from se24 a new class that has as super class ZCL_FALV... and I made this redifinition.

I cannot hide the green button but I can change his behaviour, it works.

Thanks.

I think this is good idea to simplify the popup from falv. It should inherit as in your example from ZCL_FALV, but at the end return if user clicked on continue, EXIT or any other button. Maybe message should be added in the top of page in case someone wants to raise question like - "Following documents are to be processed, do you want to continue?" or something similar.

There is a way to get rid fully of this button as there is possiblity to exclude them during the call.

So what you would need to do, is to call falv->gui_status->hide_button( 'CONTINUE' ).

Sorry it took so long, I was full day in the garden 😊
