Dear All,

In Portal Information Architecture we have four level we have to display.We are displaying two levels in horizental TLN and remaining in the third level.After creating the pcd objects while adding them to role am facing problem.I tried all the ways but they are not working.For level 1 items we have taken as Role and Level 2 item as workset and three workset.And in the fourth level pages or iviews we are adding to the hirarchy .But if I login with user and see the data then am not able to see the data properly.

Can you help me in this problem.
