I developped a data extension to define Web Service as data source. My web service make a request in a SQL server DB and then return a System.Data.Dataset object.

In design mode everything work fine. But when i try to deployed my report i get the following exeption:

The type initializer for "Microsoft.ReportingServices.Diagnostics.DataProte ction" threw an exception

So the report ends on my report server but the data source is lost on the way.

i guess it's related with security but i ain't no idea of what i should do. Any suggestion?

Thx, Choose File

PS : sorry for my broken english
