I got the following error while creating report using report wizard
“Web service request CreateReport to Report Server http://servername/ReportServer/ReportService2005.asmx failed with SoapException. Error: The Value expression for the textrun ‘txtExecutionDateTimeLabel.Paragraphs.TextRuns’ contains an error: [BC30456] ‘ConvertUtcToLocalTime’ is not a member of ‘Microsoft.Crm.Reporting.RdlHelper.DateTimeUtility'”
Re installing Reporting Extensions resolved the issue.
Hope it helps.
