The Inbox app provides detailed error reporting to help you handle files that fail validation. If you are missing an invoice that was supposed to enter your account, you should check the Inbox app to see if the document is there with an Error status. This allows you to identify exactly what caused the issue, whether the file was received via Peppol, email, or manual upload, so you can take the necessary steps to fix it.
How to access error details
Go to the Inbox app.
Locate a document with an Error status.
Double click the document.
Alternatively, you can click the three dots (⋮) in the Actions column, then select View details.
Reviewing an invalid document
Open the document from your Inbox.
A log of all the events that happened on the document appears. Look for the error and you'll see why it occurred.
If the error contains a specific error code (like BR-02), it means that the document does not meet Peppol's EN16931 model. These error code are listed here with an explanation of what caused it.
If you don't understand how to solve a specific error code, copy it and send it to our AI assistant Eva (via the messenger in the bottom right of this page) and ask her how to solve it.Use the Download button if you need to inspect the file on your computer.
Tips
Most validation errors, like incorrect formatting, need to be fixed by the person who issued the document.
For now, some invalid documents might still show a status of Processed, but you can still view their error details by clicking the three dots (⋮) in the Actions column, then select Open document. From there, you'll see the error message(s) highlighted in red.
