Oops...I missed that! If you are using stored procedures to update data, you need to add a Timestamp column to the associated table so that ADO.NET raises a concurrency exception. The MM .NET Business Layer Generator automatically adds the Timestamp column to the WHERE clause of the UPDATE stored procedure.
