International.EInvoicing.OrderX

Order-X: the Franco-German order, order change and order response, published by FNFE-MPE and FeRD — the same two who publish Factur-X, one document earlier in the chain.

It is CII, but it is not the Cross Industry Invoice. The Cross Industry Order is a different UN/CEFACT message, on version 128 of the same data types, so nothing that reads an invoice reads it and every element in the document has a different name.

All three documents are read and written. The order and the order change fill the same Order model the Peppol ordering documents do, and DocumentResult.Kind tells them apart; the order response fills OrderResponse and carries the seller's answer — a status on the document, a status on each line, and an agreed quantity beside the requested one. Unmapped content is kept verbatim and written back inside the element it sat in, after the sibling it followed — element order is normative here, so where it goes back is part of not losing it.

services.AddEInvoicing(o => o.AddOrderX());

FNFE-MPE and FeRD publish the schemas and rule sets behind a registration, so this package does not ship them. build/fetch-specs.sh order-x brings them, and then:

services.AddEInvoicing(o => o
    .AddOrderX()
    .AddOrderXSchemaFrom("specs/order-x/schema")
    .AddOrderXRulesFrom("specs/order-x/schematron"));
