issue with calling the IView from webdynpro application?

Hi All,

i am displaying the 2 tabs in my webdynpro application.

first tab - displaying time sheet details which is working fine

second tab - calling the iview of leave request application by using the PCD value given by portal .Please see the below code.

CALL METHOD o_portal_manager->navigate_absolute

       EXPORTING

         navigation_target   = c_pcd_target

         navigation_mode     = if_wd_portal_integration=>co_show_external

         history_mode        = if_wd_portal_integration=>co_no_duplicates

         use_sap_launcher    = abap_true

         business_parameters = is_parameters.

which is working fine in the portal in my id in my system.For business user its not opening the leave request application details.

Can any one please suggest me what could be the reason.

Thank you.

Regards,

Gopal
