Mexican companies very commonly issue invoices in USD, to be fulfiled
in MXN, at the official exchange rate defined by the Banco de Mexico
on the day of payment.
(Presumably, this is to insure against the volatility of the Mexican
peso.)
Odoo supports this workflow, but only if the payment is registered
directly on the invoice using the 'Register Payment' button.
If the payment is created separately, and then reconciled manually
with the invoice, a whole host of problems occur:
- the payment typically can't be reconciled fully with the invoice,
(even though that can usually be solved by manually creating
an exchange move)
- but more problematically, the amounts on the payment CFDI will
be wrong, and even manually creating an exchange move won't solve
that.
So, we absolutely need to warn users not to try to do that.
(We've been encountering lots of tickets lately in the tech-support
pipe because of users who tried this and then wonder why it doesn't
work.)
This is currently an issue in 14.0, 15.0 and master.
