What does PEPPOL-EN16931-P0111 mean? Tax Category E MUST be used when exemption reason code is VATEX-EU-J

Why did my invoice fail PEPPOL-EN16931-P0111?

If the exemption reason code VATEX-EU-J (exemption under the VAT Directive) is used, the tax category code must be E (exempt from tax). The rule enforces the fixed pairing between exemption reason codes and VAT categories.
