Do let us know what kind of reporting information or details you are intending to capture from the Reporting tool.
If I understand your questions correctly, checkout the information highlighted in the documentation (https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox):
Microsoft SQL Reporting Framework manually generating PDFs
This usage pattern does not work for Free/Shared plans due to the sandbox. However, a small set of APIs are opened for use in Basic+ plans; these APIs are designed to enable SQL Reporting framework creation of PDFs. So, these libraries should be usable for PDF generation in Basic+.
PDF generation from HTML
There are multiple libraries used to convert HTML to PDF. Many Windows/.NET specific versions leverage IE APIs and therefore leverage User32/GDI32 extensively. These APIs are largely blocked in the sandbox (regardless of plan) and therefore these frameworks do not work in the sandbox.
The following PDF generators are supported:
• SQL Reporting framework: requires the site to run in Basic or higher
• EVOPDF: See http://www.evopdf.com/azure-html-to-pdf-converter.aspx for vendor solution
• Telerik reporting: requires the site to run in Basic or higher.
• Rotativa / wkhtmltopdf: requires the site to run in Basic or higher.
• NReco PdfGenerator (wkhtmltopdf): requires subscription plan Basic or higher
