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.
Please refer to our article on ADM: Access Document (aCloud Document) files not uploading due to Error 'System.IO.FileNotFoundException: Could not find file' for more information and advise on how to resolve this.
**Please note that any Invoice which has returned a Document Export Failed, along with this detailed error will likely mean:
The Invoice has successfully imported into Dimensions
The Invoice in Dimensions will be missing a ADM Document
Any attempts to retry 'verify' of the Invoice in Capture will lead to a duplicate Invoice being processed into Dimensions
The second/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.
