The UserID of the user that made a definition for the variable specified by Path or the local user if not specified.
Usage
Upon being given a valid cloud variable Path, the component will drive the value of the Target with the value of the cloud variable owned by the local user. If OverrideOwner is specified, the field will only be driven to the value for the user specified in OverrideOwner. Otherwise, the field will take the value of the FallbackValue.
