Troubleshooting Tips
Display Cannot Find Data
When a display does not receive data, the problem may be one of the
following:
 The network is down.
 A display has been moved from one PC to another and Node
Identifiers to the Server(s) need to be re-established through the
Connections dialog box (page 6).
 An ODBC Data Source may have been altered, causing the dataset to
fail to return data.
