Bw Project report with dynamic parameters

Hi all,

We Have BW project's report & we want to change the

WBS Hierarchy dynamically from the portal.

The problem is this,

When we add this parameters to url:

&FILTER_IOBJNM_1=0WBS_ELEMT&FILTER_NODE_IOBJNM_1=0WBS_ELEMT&FILTER_VALUE_1=P2.2005.999

We can see only the current WBS with out the hierarchy connect to this WBS .

Can some one help us with this?
