So I've created a DLL assembly using the BIDS tools and Visual Studio, deployed the DLL to the correct folder on the BIDS dev workstation and on the server where Reporting Services is hosting the report. Everything is working fine. So, how does an "ordinary" user access this report since the dependent DLL is sitting on the server and not on the client where the Report Builder's report processor is running. Does the IT staff have to copy the DDL to somewhere on the client's system so the Report Builder .EXE can see it? If so, where? What's the "best practice" method here?__________________________________________________________________ William Vaughn Mentor, Consultant, Trainer, MVP http://betav.com http://betav.com/blog/billva http://www.hitchhikerguides.net Hitchhikers Guide to Visual Studio and SQL Server (7th Edition) Please click the Mark as Answer button if a post solves your problem!

Hi William, "Does the IT staff have to copy the DDL to somewhere on the client's system so the Report Builder .EXE can see it? If so, where?" Yes, the DDL must be deployed on clients' system. I recommend that you put the dll into clients' GAC.
