Sometimes reports are too large to export as a PDF in the Reports module. If this is the case, these reports can be found in Smart Reports.
To access Smart Reports, you can head to the System Menu & select Catalogue > File Upload.
Once in File Upload, you can navigate to the Smart Reports folder where you can find your PDF file.
Please Note: The Smart Report folder is not a shared folder between user profiles. This means you can only access your PDF on the same user profile that generated it.
