If transactions in the Quality Control queue show a status of Error, use the sections below to identify the cause and resolve it.
If the error is **KTM Server Error**
This is likely caused by the KTM Service going down while the transaction was being processed. To resolve it, unreject the batches — this allows the invoices to be reprocessed by the KTM Server and arrive at Validation.
If the error is **Export errors**
This means the transactions failed to export to the Safe Financials system. This is likely caused by data that the Export Connector cannot accept or reject due to a lack of error handling. The invoices will need to be removed and pushed back through the system from the start. Contact support for help with this.
