BR-FR-CDV-13_MDT-129
Validation message
Explanation
The sender party identifier (MDT-129) is mandatory — except in specific status cases.
How to fix
Add the sender identifier. (Typically a software-side issue, not user input — raise this with your invoicing software vendor; if you're receiving the invoice, ask the sender to address it with theirs.)
Applies to
- Factur-X / FR (CDAR)
