       w_url   TYPE char255.
SELECTION-SCREEN : BEGIN OF SCREEN 1001.
PARAMETERS: rb_alv RADIOBUTTON GROUP rb1,
             rb_graph RADIOBUTTON GROUP rb1.
SELECT-OPTIONS : s_fkdat FOR vbrk-fkdat.
SELECTION-SCREEN END OF SCREEN 1001.
START-OF-SELECTION.

Hi neran,
               before u split the container, u have to create the container.
create object cont                                           "Creating Docking Container
       exporting
     side                        = 4                                     "At Bottom
     ratio                       = 70
       exceptions
         cntl_error                  = 1
         cntl_system_error           = 2
         create_error                = 3
         lifetime_error              = 4
         lifetime_dynpro_dynpro_link = 5
         others                      = 6
     if sy-subrc <> 0.
       message id sy-msgid type sy-msgty number sy-msgno
                  with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
     endif.
"u have to pass the container name
   IF splitter IS INITIAL.
     CREATE OBJECT splitter
       EXPORTING
         parent  =  cont " pass the container name
         rows    = 2
         columns = 1
         align   = 15. " (splitter fills the hole custom container)
   ENDIF.
"Then u need another objects, which ref to  cl_gui_container, to get the splitted containers
