XRechnung error BR-DE-2: seller contact group missing
BR-DE-2 requires that every XRechnung contains the SELLER CONTACT group (BG-6) — the seller's contact details. This group holds the contact point (BT-41), telephone number (BT-42) and email address (BT-43).

Affected field
cac:AccountingSupplierParty/cac:Party/cac:Contact (UBL) / ram:SellerTradeParty/ram:DefinedTradeContact (CII)
Cause
The seller party contains no Contact element. Many accounting systems omit a contact because EN 16931 makes the group optional — XRechnung makes it mandatory.
Fix
Add a cac:Contact element under the seller party with Name (BT-41), Telephone (BT-42) and ElectronicMail (BT-43). XRechnung requires all three (see BR-DE-5, BR-DE-6, BR-DE-7).

Frequently asked questions
Why does XRechnung require a contact when EN 16931 does not?▼
XRechnung is a CIUS (restriction) of EN 16931 for the German public sector. It makes several fields that EN 16931 leaves optional mandatory — including the seller contact group (BG-6) — so the recipient always has someone to reach.
Which fields belong to the BG-6 group?▼
The contact point / name (BT-41), telephone number (BT-42) and email address (BT-43). If one of these is missing, the follow-up rules BR-DE-5, BR-DE-6 or BR-DE-7 fire respectively.
