If you are seeing this Error it relates to a problem with the Access Capture Broker Service uploading a copy of the document to ADM.
See the article on ADM: Access Document (aCloud Document) files not uploading due to Error 'System.IO.FileNotFoundException: Could not find file' .
📌 Note: Any invoice that returns a Document Export Failed error along with this error will likely mean:
The invoice has successfully imported into Dimensions
The invoice in Dimensions will be missing an ADM document
Any attempts to retry 'verify' of the invoice in Capture will lead to a duplicate invoice being processed into Dimensions
The second or duplicate process of this invoice may be (as a whole) successful - as this problem is reported to be intermittently occurring and only on very large batches of Invoices being sent from Capture at any one time.
