The Data Exchange Server requires a reconciliation monitor to track events and update the status of the reconciliations. The schedule you set for the reconciliation monitor determines how often the Data Exchange Server updates the status of the reconciliations. If you do not create reconciliation monitors, the Data Exchange Server does not update the reconciliation status of any event.

When a reconciliation monitor runs, the Data Exchange Server updates the status of the reconciliations for the events within the scope of the monitor. If you create multiple reconciliation monitors with the same scope and the monitors run at different times, the monitors find the reconciliations at different stages. When the first monitor runs and finds an event that falls within the scope of the monitor, it can change the status of the event. If the status changes, the other monitors do not find the same event because the new reconciliation status does not fall within the scope of the monitor.

For example, you create reconciliation monitor A to track reconciliations for account 100 with status Reconciled after timeout and schedule it to run at 8:00 a.m. every day. You also create reconciliation monitor B to track reconciliations for account 100 with status Reconciled after timeout and schedule it to run at 10:00 a.m. every day. When monitor A runs, the Data Exchange Server finds one event for account 100 with the status Reconciled after timeout. It changes the status to Reconciliation complete. When monitor B runs, the Data Exchange Server does not find any event for account 100 with status Reconciled after timeout.

You can configure the reconciliation monitor to notify you of the events that fall within the scope of the reconciliation monitor. You can use the reconciliation monitor to determine whether the reconciliations are completed in a timely manner. If a large number of reconciliations do not complete within the timeout limit, you might need to raise the timeout limit or modify the document reconciliation process.
