naviagate_absolute is not working first time after login

Hi Experts,

I wrote a code for navigating to the portal iview in webdynpro ABAP using below code

CALL METHOD lr_port_manager->navigate_absolute

      EXPORTING

        navigation_target = 'ROLES://portal_content/test/test123&NavMode=3'

        navigation_mode   = if_wd_portal_integration=>co_show_inplace

        history_mode = if_wd_portal_integration=>co_allow_duplicates.

If I login to the portal first time it is not working. But if I refresh the browser and open the same application , I am able to navigate perfectly.

Again if I close all the browsers and refresh the cache and try to login again, it is not working.

Can anyone please help me on this issue. Thank you.

Regards,
