3794657 - france e-invoicing b2b 2026: unit of measure iso code requirement and missing aif mapping

Symptom

  • Integration with French authorities for electronic invoicing and reporting requires standard ISO code for unit of measure (UN/ECE Rec. 20/21), for example mapping UoM PC to ISO code H87 (Piece).
  • The system is not configured with the UN standard ISO code for some UoM.
  • Attempting to use AIF value mapping (/EDUBL, UNIT_OF_MEASURE_CODE) to map PC/EA to H87 is not available for invoices in the b2b 2026 scenario.
  • C18 - Error "[BR-CL-23] Unit code MUST be coded according to the UN/ECE Recommendation 20 with Rec 21 extension".
