This setting specifies the default data source configured on the Application Server.
Within the <![CDATA[ ]]> tag, enter the name of the data source to be used if Epic passes in an environment ID that is blank, invalid, or not mapped to a data source (as described later in this procedure). If the ServiceDatasource is blank in this situation, the Scan Acquisition Server uses the data source configured in the Application Server's Web.config file.
<ServiceDatasource><![CDATA[dmdatasource]]></ServiceDatasource>
If a valid environment ID is passed in, then data source mapped to the ID is used.
