If you have defined multiple configurations on multiple servers, you can select a server and one of its configurations as the active configuration. The active configuration will be used for subsequent validations. On placing the cursor over the Tools | Raptor Servers and Configurations command (see screenshot below), a submenu appears that contains all the added servers, together with the configuration of each. Select the server configuration you want to make the active configuration. In the screenshot below, the xbrl configuration of the server named Raptor-01 has been selected as the active configuration (indicated by the green arrow).
See the section RaptorXML(+XBRL) Server for an overview of how to use Raptor from within XMLSpy.
