This method does not need a seperate screen but a selection screen is must. 

Data: 
dock_container type ref to cl_gui_docking_container, 
tree1 type ref to cl_gui_alv_tree_simple. 


*A docking container does not explicitly need a screen for it.It can be 
*placed on the selection screen itself.Here we are using the screen 
*which is used for the alvgrid. 
*First create a docking container with dock at left 


if dock_container is initial. 

create object dock_container 
exporting 
* PARENT = 
repid = g_repid 
dynnr = g_dynnr 
side = dock_container->dock_at_left 
extension = 300 
* STYLE = 
* LIFETIME = lifetime_default 
* CAPTION = 'jkhbnjkhk' 
* METRIC = 4 
* RATIO = 80 
* NO_AUTODEF_PROGID_DYNNR = 
name = 'dockkkkkk' 
* EXCEPTIONS 
* CNTL_ERROR = 1 
* CNTL_SYSTEM_ERROR = 2 
* CREATE_ERROR = 3 
* LIFETIME_ERROR = 4 
* LIFETIME_DYNPRO_DYNPRO_LINK = 5 
* others = 6 
. 
endif. 

*Secondly create the field cat for the alv to be disp in dock container 
call function 'LVC_FIELDCATALOG_MERGE' 
exporting 
* I_BUFFER_ACTIVE = 
i_structure_name = 'ZC9_STRUCT' 
* I_CLIENT_NEVER_DISPLAY = 'X' 
* I_BYPASSING_BUFFER = 
changing 
ct_fieldcat = i_fcat[] 
* EXCEPTIONS 
* INCONSISTENT_INTERFACE = 1 
* PROGRAM_ERROR = 2 
* OTHERS = 3 
. 
if tree1 is initial. 

*Thirdly create the tree1 object for the ALV with parent as docking 
*container 
create object tree1 
exporting 
* I_LIFETIME = 
i_parent = dock_container 
* I_SHELLSTYLE = 
* I_NODE_SELECTION_MODE = 
*cl_gui_column_Tree=>NODE_SEL_MODE_SINGLE 
* I_HIDE_SELECTION = 
* I_ITEM_SELECTION = 'X' 
* I_NO_TOOLBAR = 
i_no_html_header = '' 
* I_PRINT = 
* EXCEPTIONS 
* CNTL_ERROR = 1 
* CNTL_SYSTEM_ERROR = 2 
* CREATE_ERROR = 3 
* LIFETIME_ERROR = 4 
* ILLEGAL_NODE_SELECTION_MODE = 5 
* FAILED = 6 
* ILLEGAL_COLUMN_NAME = 7 
* others = 8 
. 
*Finally create a tree with the below method. (Sort table need to be *passed) 
call method tree1->set_table_for_first_display 
exporting 
* I_BYPASSING_BUFFER = 
* I_BUFFER_ACTIVE = 
* I_CONSISTENCY_CHECK = 
i_structure_name = 'ZC9_STRUCT' 
it_list_commentary = pt_list_commentary 
i_logo = l_logo 
* IS_VARIANT = 
* I_SAVE = 
* I_DEFAULT = 'X' 
is_layout = gs_layout_tree 
* IS_PRINT = 
* IT_SPECIAL_GROUPS = 
* IT_TOOLBAR_EXCLUDING = 
* IT_HYPERLINK = 
* IT_ALV_GRAPHICS = 
* IT_EXCEPT_QINFO = 
changing 
it_outtab = itab[] 
* it_fieldcatalog = i_fcat1[] 
it_sort = gt_sort_grid[]
