If an invoice is rejected because a certain value has exceeded a threshold, the real problem may be missing or invalid invoice data. For more information, see Troubleshooting Missing or Invalid Invoice Data. If the data is being pulled from the time & billing system correctly, and the electronic billing file is being created correctly, the Time & Billing system data may need to be corrected to meet the client's requirements.
If you are still not able to resolve the issue, contact support. You may be asked to save the raw invoice data. To do this, see View Time and Billing Raw Data.
