The seller contact is missing
The `SELLER CONTACT` group (BG-6) must be provided.
Only the issuer holds this value: Factlint reports it and never fabricates it. Test your invoice to find out whether it is affected.
The message your validator prints
Copied verbatim from the sealed artefact: this is the exact sentence the check prints when this rule fails.
[BR-DE-2] Die Gruppe "SELLER CONTACT" (BG-6) muss übermittelt werden.

Common searches around this code
These phrases mirror what an integrator searches for: code, syntax, rule, business field and correction.
Test your file with this error in mind
Upload the invoice involved: the report will say whether this code appears, where it appears in the document, and whether Factlint can only report it or also fix it.
To automate this check in an ERP flow, call the validation API and link every returned code to its public page.
Why this error happens
XRechnung wants an invoice to name someone reachable at the seller. The group carries three elements, each checked by its own rule — BR-DE-5, BR-DE-6 and BR-DE-7; this finding says the whole group is absent, so the other three follow it.
How to fix it
Add the contact to your seller record. Factlint reports it as `needs_input` and never fabricates a default value.
