Failed to update bill record

On rare occasions, bad data can be generated against the Operational side of an invoice. Trying to post the record will result in the below error message.

To resolve this issue, please follow the steps below:

1. Reject the invoice.
2. Delete the "Pending" invoice completely. This is so the system generates a new Operational invoice number.
3. Create the invoice again.
4. Approve and Post.
