EN 16931
FATAL
This is a VAT category rule for VAT category. When any line, allowance or charge uses this category, the standard requires a matching, internally consistent VAT breakdown (seller identifiers, category rates, taxable and tax amounts).
How to fix it
- Check every line using this VAT category against the requirement in the rule text.
- Make sure the VAT breakdown (BG-23) contains exactly one entry for this category, with consistent rate and amounts.
- For exemption-style categories, provide the exemption reason text or code where required.
Official rule text
In a Document level allowance (BG-20) where the Document level allowance VAT category code (BT-95) is "IPSI" the Document level allowance VAT rate (BT-96) shall be 0 (zero) or greater than zero.
