ReportViewer OK in Development, but no data in deployment

[IrvineCAGuy]

I have a rdlc report that displays data passed to the form from a dataset created in memory.
On my development platform (Windows 7 with VS2010) the report displays both the Reports Parameters passed to it
Parameters = New ReportParameter("DeliveryDate", strDeliverDate)
Me.ReportViewer1.LocalReport.SetParameters(Parameters)
and the dataset set using
DeliveryDataTableBindingSource.DataSource = DeliveryOrders.oDeliveryDataTable

However, when I run the application on the deployment server (Server2008R2) the report display only the parameters passed, and does not process the Dataset values.

Might anyone know what this could be caused by? Where to look to fix? Thanks.
