Ian,

First off I selected dynamic SQL and the command type was still set to stored procedure and secondly the error persisted. When I issue a saverow I get the following error stream:

Can you zip up your business object project and send it to me? It will be easier for me to see what's going on. Also, if you can detach your SQL Server database, zip it up, and send it to me that would be helpful too.
