SURCHARGE_RATE_NOT_ACCEPTED_ON_DATE

When it happens

The equivalence surcharge and the VAT rate of a line form a pair AEAT does not accept on the operation date: with VAT at 5 %, 0.5 up to 2022-12-31 and 0.62 from 2023-01-01; 0.26 with 2 % and 1 with 7.5 % only from 2024-10-01 to 2024-12-31.

How to fix it

Use the surcharge of the pair for that date, or omit equivalence_surcharge_rate and let it be derived from the VAT on the operation date.
