There are multiple locations where you can set SAS Web Report Studio properties:
In standard deployments of SAS® Web Report Studio 4.4 on SAS® 9.4M9 (TS1M9), updates made via the Advanced tab in the Properties dialog box (under Configuration Manager ► SAS Application Infrastructure ► Web Report Studio) should be honored unless overridden by specifying the same property in the XML configuration files mentioned above.
If changes made in SAS Management Console are not honored, consider adding the property to either the WebReportStudioProperties.xml or LocalProperties.xml.
