Microsoft Dynamics CRM Online uses RDL Sandboxing that prevents reports from uploading or running if they contain code that uses disallowed methods.
Reports in Microsoft Dynamics CRM Online run in sandbox mode, and to do it, RDL sandboxing is enabled in Microsoft SQL Server Reporting Services. So certain features might not be available in Microsoft Dynamics CRM Online. For example, custom code in your report definition won't work. For more information, see Enable and disable RDL sandboxing for Reporting Services in SharePoint integrated mode.
When RDL Sandboxing is enabled, the following features are disabled:
- Custom code in the <Code> element of a report definition
- RDL backward compatibility mode for SQL Server 2005 Reporting Services custom report items
- Named parameters in expressions such as DateFormat or NameSpace
When RDL Sandboxing is enabled, only certain classes and methods can be used in a custom FetchXML report. The following list is the classes that are allowed, and beneath each class are the available methods for use in Microsoft Dynamics CRM Online reports:
