External window without title

Hi Friends,

I am using Function Module CREATE_EXTERNAL_WINDOW to show PDF in an external window.

I used UI as Linktoaction.

Problem is that - URL is being shown as Title on top of window.

and that can be used by employee to see other employee details.

Is there any way to Delete/EDIT title of external window.

I have used following code

CALL METHOD LO_WINDOW_MANAGER->CREATE_EXTERNAL_WINDOW

EXPORTING

URL = LV_HOSTNAME

TITLE = 'Form 16'

MODAL = ABAP_FALSE

HAS_MENUBAR = ABAP_FALSE

IS_RESIZABLE = ABAP_TRUE

HAS_SCROLLBARS = ABAP_TRUE

HAS_STATUSBAR = ABAP_FALSE

HAS_TOOLBAR = ABAP_FALSE

HAS_LOCATION = ABAP_FALSE

RECEIVING

WINDOW = LO_WINDOW.

CALL METHOD LO_WINDOW->SET_WINDOW_TITLE

EXPORTING

TITLE = 'Form 16'.

LO_WINDOW->OPEN( ).
