What causes the BR-DE-22 error?

XRechnung requires all EmbeddedDocumentBinaryObject filename attributes to be unique. This error occurs when two or more attachments have the same filename.

How do I fix BR-DE-22?

Rename duplicate attachments to have unique filenames, e.g., invoice.pdf and invoice-2.pdf instead of two files named invoice.pdf.

Why must filenames be unique?

German authorities require unique filenames to properly identify and process attached documents.

Can BR-DE-22 be automatically fixed?

Yes, Invoice Navigator can automatically rename duplicate attachments by adding a numeric suffix.
