Invoice type code 326 or 384 are only allowed when both buyer and seller are German organizations
Invoice type code 326 (partial invoice) or 384 (corrected invoice) is used, but the parties are not both German organisations.
Peppol allows these two codes only between German trading partners. Use 380 and describe the situation in the invoice note, or reference the corrected invoice through BG-3.
