ALV USER COMMAND.

Source : http://abapjoy.blogspot.com

Generally, we implement the ALV button action for the event that user push the button.

1. ALV Level : ALV Event implementation

METHOD handle_command.     DATA : l_scroll TYPE lvc_s_stbl.     CASE e_ucomm.       WHEN ‘ALV command’.           ‘Implementation of method ~~’.     ENDCASE.   ENDMETHOD.                    "handle_user_command

There is another useful way to integrate all user action of ALV within SCREEN level.

 When user click the button on ALV, if you call the method ‘ SET_NEW_OK_CODE’ of class ‘CL_GUI_CFW,

you can implement the same function of calling alv hander method. That is, the user command on ALV to screen PBO module.

1. ALV event

METHOD handle_command.     DATA : l_scroll TYPE lvc_s_stbl.     CASE e_ucomm.       WHEN ‘ALV command’.          CALL METHOD cl_gui_cfw=>set_new_ok_code          EXPORTING              new_code = ‘ALV command’.       ENDCASE.   ENDMETHOD.                    "handle_user_command

 2. screen PAI command implementation.

MODULE user_command_0100 INPUT.   CASE sy-ucomm.     WHEN ‘ALV command’.        ‘implement of alv function’ NDCASE. ENDMODULE.                 " USER_COMMAND_0100  INPUT
