If your report contains the parameter Globals!ReportName and you decided to move this report from SharePoint to Native Mode it is very likely that you have to add &”.rdl” to the end since Globals!ReportName does not contain the extension in Native Mode.
For the report to work on both environments add the following code under Report Properties > Code
Public Function ReportExtension(ByVal ReportName As String) As String If Not ReportName.ToLower.Contains(".rdl") Then ReportName += ".rdl" End If Return ReportName End Function
Then just call it by using the code
