How to preview standard MDM Webdynpro Components?

Hi,

is there any specific role required to see the preview of the Search , Result set and Item details view configured by MDM web dynpro configuration manager using below url

http:// : /webdynpro/dispatcher/ sap.com/tc _mdmwdcomps_masterwd/MASTER?proj=<Project_Name>&rs=<ResultSet_Name>&s=<Search_Name>id=<ItemDetails_Name>

I am getting the error that "You are not authorized to use MDM Web Dynrpro Test Application" while trying to rum the above url with proper parameter. I have already administrative access assigned.

Thanks

Ravindra
