When adding an SSRS Report to a Synergy Enterprise Home Page, You need to be aware of:

As you Save (or Modify) a Report that you have built and are placing it into Synergy on the Reporting Services Integration: Management page, it is imperative to make sure that “Show as Web Part” check box is selected for the report.

If this is not done, the report will not be available for displaying on a Home Page widget.

If the selection (on the report list tree) for a report web does not display the report you wish to use, look to this possible reason – Does the User have the right to view or access these reports?
