Problem Description#

To allow the buyer to identify the supplier automatically, at least one of Seller identifier (BT-29), Seller legal registration identifier (BT-30) or Seller VAT identifier (BT-31) must be present.

ERROR

XRechnung 3.0

Context and Significance#

Buyer ERP systems automatically match suppliers by these identifiers. If none is present, the invoice falls into a manual matching queue and payment is delayed.

Solution#

Populate at least one of BT-29, BT-30 or BT-31 in the Seller party block.

Valid Examples#

  • BT-31 = "DE123456789"
  • BT-30 = "HRB 12345"
  • BT-29 = "GLN 4012345000094"

Invalid Examples#

  • Seller party with name and address only, BT-29/BT-30/BT-31 all absent
  • BT-31 cleared because the seller is not VAT-registered, but BT-30 also missing

Technical Details#

Affected Fields

BT-29 Seller identifier, BT-30 Seller legal registration identifier, BT-31 Seller VAT identifier
