Error at the time of REPORT to generate in export to excel

Hi experts,

error occur at the time of report generation in navision 2013r2 please advise…

A call to Microsoft.Dynamics.Nav.OpenXml.Spreadsheet.WorkbookWriter.Dispose failed with this message: Store must be open for this operation.

Please Check the specified field . Please elaborate the question. In my opinion there is some Condition on on pre report trigger which is miss matching. Also Please check the report parameters where it is creating the Excel if generated.

In the following path C:\Program Files\Microsoft Dynamics NAV\70\Service go to CustomSettings file and open the notepad as administrator.
Try to give the value for OperationTimeout as MaxUploadSize.
If it won’t resolve
