Rule reference

BR-04 An invoice must have an invoice type code (BT-3), but invoiceTypeCode was set to ""

An invoice must have an invoice type code (BT-3), but invoiceTypeCode was set to "". The type code is what distinguishes a commercial invoice from a partial invoice, a correction or a self-billed document, and receiving systems branch on it before they read anything else. An empty string is not the same as omitting the field: omit it and this library supplies the default "380"; set it empty and you have explicitly asked for a document with no type.

This rule is implemented and its error payload below is real, but the long-form write-up — normative text, worked example, divergence note — is not written yet. Everything the library knows about this rule is on this page. Ask and we will prioritise it.
