Hi,

at the top of the program :

CLASS lcl_event_receiver DEFINITION.
  PUBLIC SECTION.
    METHODS handle_double_click
      FOR EVENT double_click OF cl_gui_alv_grid
        IMPORTING e_row e_column.
ENDCLASS.

After the set_table_for_first_display :

  IF obj_grid_event IS INITIAL.
    CREATE OBJECT obj_grid_event.
      SET HANDLER obj_grid_event->handle_double_click
          FOR obj_grid.
  ENDIF.

  CLEAR v_ok_code.

And the class with the action on double-click :

*---------------------------------------------------------------------*
*       CLASS LCL_EVENT_RECEIVER IMPLEMENTATION                       *

         INTO is_data
         INDEX e_row.
    CHECK sy-subrc EQ space.


*   Selon la colonne on effectu différentes actions.
    CASE e_column.

      WHEN 'MATNR'.

        SET PARAMETER ID 'MAT' FIELD is_data-matnr.
        CALL TRANSACTION 'MM03' AND SKIP FIRST SCREEN.

      WHEN 'IBASE'.

        SET PARAMETER ID 'IIB' FIELD is_data-ibase.
        SET PARAMETER ID 'DSE' FIELD p_date.
        CALL TRANSACTION 'IB53' AND SKIP FIRST SCREEN.

    ENDCASE.

  ENDMETHOD.
