Linked Hierarchy of Parameters

The sample reports included with the DataLink Viewer software demonstrate a hierarchy of parameters whereby the values selected by the user in response to the Prompt_Product_Types.rpt parameter restrict the values available for selection in the Prompt_Products.rpt parameter:

The DataLink Viewer always starts from the bottom of the hierarchy for each parameter!
Hence, we are going to be prompted first for Product Types before we select Products within those Product Types.
