Hi,

I have a small requirement in ALV Tree

example

Name Description subscreen 0101

xyz xyz desc (double click on this) name = XYZ

ABC abs desc descrip = xyz desc

This is what the requirement is:

Hi Bhavana,

IF NOT r_ucomm IS INITIAL.

CASE r_ucomm.

WHEN '&F03'.

SET SCREEN 100.

LEAVE SCREEN.

endif.

Refer the below code for setting the registering the event.

CALL METHOD tree->get_registered_events

IMPORTING

events = l_events_s.

l_event-eventid = cl_gui_column_tree=>eventid_item_double_click.

APPEND l_event TO l_events_s.

CALL METHOD tree->set_registered_events

EXPORTING

events = l_events_s

EXCEPTIONS

cntl_error = 1

cntl_system_error = 2

illegal_event_combination = 3.

CREATE OBJECT l_events_receiver.

SET HANDLER l_events_receiver->handle_item_click FOR tree.

CLASS lcl_events_receiver DEFINITION. "#EC *

PUBLIC SECTION.

METHODS:

handle_item_click FOR EVENT item_double_click OF cl_gui_alv_tree

IMPORTING node_key fieldname.

ENDCLASS. "lcl_handle_events DEFINITION

CLASS lcl_events_receiver IMPLEMENTATION.

METHOD handle_item_click.

PERFORM employee_data USING node_key fieldname.

CALL SCREEN 300.

ENDMETHOD. "HANDLE_ITEM_DOUBLE_CLICK

ENDCLASS. "lcl_events_receiver IMPLEMENTATION

Thanks.
