Hello All,

below is the code for the same,
data l_componentcontroller type ref to ig_componentcontroller .
  data l_api_componentcontroller type ref to if_wd_component.
  data l_sapgui_manager type ref to cl_wdr_sapgui_integration.
  l_componentcontroller =   wd_this->get_componentcontroller_ctr( ).
  l_api_componentcontroller = l_componentcontroller->wd_get_api( ).
  l_sapgui_manager = l_api_componentcontroller->get_sapgui_manager( ).
  if l_sapgui_manager is not initial.

  endif.
But the object l_sapgui_manager  is not getting instantiated. please let me know if i am calling the right method or  the code is wrong???

Hi Chandra,
You need to Initialise the  l_sapgui_manager before you are accesing. see the folowing code i initialised my select options component.This code can be obtained from Wizard also. I hope this will help you.
Please do this in the WDDOINIT of component controller. So that it will be inistatiated before you are accessing the component.
** initialize select options component for query creation
  lr_cmp_usage = wd_this->wd_cpuse_sel_options( ).
  wd_this->usage_name = lr_cmp_usage->name.
  IF lr_cmp_usage->has_active_component( ) IS INITIAL.
    lr_cmp_usage->create_component( ).
  ENDIF.
  l_ref_interfacecontroller = wd_this->wd_cpifc_sel_options( ).
  wd_this->mr_selopt_helper   = l_ref_interfacecontroller->init_selection_screen( ).
Warm Regards,
Vijay.
