## When it happens

The exchange invoice is recorded with VeriFactu as `F3`, which only replaces simplified invoices the AEAT has accepted, and the record of one of `simplified_invoice_ids` is still pending. Nothing is issued.

## How to fix it

Wait until that simplified invoice's record is accepted (`verifactu.submission_status` reads `ACCEPTED`, or the `verifactu.status.updated` webhook tells you), then send the exchange again.

## Retry

Retry the same request unchanged, with the same `Idempotency-Key` if you sent one. Wait first, and honour the `Retry-After` header when the response carries it.
