This is correct behavior. If you use a mix of Vision and SQL Server, and use FILE-PREFIX with a value containing multiple directory levels such as \usr\data\ar, then this information is stripped from the file name before it opens. This configuration variable prevents this
When set to the default value of TRUE (ON, YES, 1), then the interface behaves as it always has. When set to FALSE (OFF, NO, 0), the interface ignores the name.
