OTM Reports VPD issue

Hi

I am having trouble with setting the VPD for an OTM Report using Oracle Reports Builder
I want to set the VPD according to the multiple roles for a user. The issue is that no matter which role I switch to it returns values based on the primary role.
Currently I am using the below instruction in the report trigger
set_vpd(: p_gl_user)

Appreciate any help i can get.

Regards,

Varun
