I'm not sure I follow your report logic.  How is the date range determined for each report?  You can easily design your report to generate things like year to date, month to day, etc off of a single parameter.

uh...no.  

If the datasource is dimensional, then you need to create a dataitem that unions four filtered set expressions together.  The whole expression will look :

Union(
  union(
    filter([cube].[Time].[year].[year],?ReportType?='Yearly'),
    filter([cube].[Time].[year].[month],?ReportType?='Monthly')
  ),
  union(
     filter([cube].[Time].[year].[week],?ReportType?='Weekly'),
     filter([cube].[Time].[year].[day],?ReportType?='Daily')
  )
)

The key to this is the filter expression; only one of them will be "true", which means that the other three expressions  will return an empty set.  ENd result is that you only get the set of members for the selected time period.  Substitute the level expression for whatever the required set expression is for each report type.
