Rex,

>How about using one data table and a data view of that data table filtered on the primary key to get the individual datarow? I looked at the mmBusinessObject.DataSet property, but it is of type DataSet, not mmDataSet, so I cannot keep the view there. Where can I save the data view so I can access it later?

Check out the MM .NET Dev Guide topic "Working with DataViews". It contains information on persisting DataViews for later use.

Best Regards,
