When I try to sign an invoice with withholding tax and IVA tax, I get the next error:
PAC no firmó el CFDI:
- Código: CFDI40999 - Error no clasificado.
- Mensaje: The required attribute 'Impuesto' is missing.
But when I try to sign an invoice with only IVA tax, the invoice signature is correct.
I have the localization for México and all modules are up to date.
Does anyone know how to correct this error?
