This Gauge32 field carries the numeric error code returned by the remote transfer operation for a recurring configuration-export policy that periodically exports the full UCS configuration (not backup state) to a remote server, when one occurred. An admin troubleshooting a failed CfgExportPolicy uses this code together with the accompanying RmtErrDescr text to distinguish, say, an authentication failure against the remote server from a disk-full condition on that server, without having to log into the remote host itself. A value of 0 typically means no remote error occurred; a nonzero value pairs with a specific error description explaining what the remote server rejected.
