Users may find that, after running the LO / CRM Connector Sync, a transaction may fail. After placing the transaction into "Queued for Reprocess" status, the transaction remains in this status after the next time that the LO/CRM Sync runs.
The most common cause of this issue is that the transaction has been refunded from Luminate Online. Please verify, using your merchant services account, that the transaction has been refunded. If this is the case, set the transaction to "Do not process" in CRM using the down chevron menu on the transaction line to prevent this record from attempting to sync in the future.
