When an SES submission fails
Diagnose the real error the Ministry returned, fix the guest data that caused it, and resubmit the report within the legal deadline.

Before you start
Spot the error
When SES Hospedajes rejects a report, it doesn't disappear from your dashboard — it stays in Submissions, with a visual flag on its filing pipeline. To see them all together, open Submissions and filter by status "Error" — you'll get only the reservations the Ministry sent back with a problem.
Each row shows a small pipeline — Submitted, Validated, Queued, Processing, and the final outcome — and when something fails, that last step turns red and reads "Partial errors" or "Rejected" instead of "Accepted".

Open the detail
Click the row to open its full detail page. Near the top, the "Police Submission" card shows "Error" in red, and further down, next to each affected traveller, you'll see the "Partial errors" or "Rejected" label and the exact text the Ministry returned.
That text is literal — it's SES Hospedajes' own response, not a BookCheckin translation. For example, for the case in this manual SES returned: "[1] Validación: El código postal ha de ser longitud 5" ("the postal code must be 5 digits long"). It's the most reliable clue you have — it almost always names, precisely, which field needs fixing.

The most common errors
Postal code: SES requires exactly 5 digits. An incomplete code, one with letters, or one copied from another country (as in the example above) is always rejected. The same applies to the municipality code when the filing includes one.
Split compound surnames: if a surname like "Del Pino" or "De la Torre" is stored split in a way that leaves the particle ("DEL", "DE LA"…) alone in the first- or second-surname field, the Ministry rejects it as an incorrect value.
Nationality or country code: a malformed country code, or one inconsistent with the guest's document, also triggers a validation error.
Duplicate submissions: if the same document number was already reported for that reservation, SES returns a duplicate-communication error instead of creating a new report.
Document support-number format: a DNI support number is 3 letters plus 6 digits (e.g. BMP123456); a NIE or TIE support number is the letter E plus 8 digits (e.g. E12345678). Any other shape is rejected.
Credential or authentication errors: if the Ministry username or password has changed or is incorrect, the submission fails on authentication before it even reaches guest-data validation. Re-enter the username and password from the property's Legal tab.
Fix the data
SES Hospedajes has no operation to "edit" an already-filed report — the only way to correct it is to cancel it and file again. So to fix a guest, first cancel the submission from "More actions → Cancel submission": the guest's check-in link stays active, but the report is no longer filed.
Once the submission is cancelled, two actions appear next to each guest: "Re-collect" blanks their details so they re-enter them on the check-in form — useful when the guest themself entered the bad value, like an address or postal code. "Remove" deletes the guest from the reservation entirely, for when they were added by mistake.
Once the guests causing the problem are fixed — or removed — the "Re-file corrected submission" button reports the whole reservation to the Ministry as a fresh lote.

Cancelling, correcting and re-filing are only available to owner or manager accounts. Staff can see the error, but not correct it.
Resubmit
If the error doesn't need you to touch the guest's data — say, it was a one-off connection hiccup with the Ministry, or the platform already fixed it automatically (next step) — there's no need to cancel anything: the "Retry Ministry" button in the page header resends the same report as-is.
The same action also sits next to each guest, in case only one of them failed while the rest of the reservation is already accepted — so you don't resend guests who are already correctly registered.

Errors that fix themselves
Not every error needs you to step in. BookCheckin automatically reviews every report the Ministry sends back with an error and, for a specific, limited set of cases, fixes it and resubmits it without you doing anything: a duplicate document number within the same reservation (keeps the most recent one), a blank guest slot that slipped into the filing (excluded from the batch), a nationality or country code in a different format than SES expects (normalized to the 3-letter standard), and a compound surname split in a repairable way, like a stray "DEL" left alone in the first-surname field (automatically recombined).
The error in this manual — the postal code — isn't on that list: BookCheckin can't invent a valid postal code, so that kind of error always needs you (or the guest, via "Re-collect") to fix it. The same goes for a malformed email, a name the Ministry rejects outright, or any error the system doesn't recognise.
The legal 24-hour deadline to report to SES Hospedajes still applies from the guest's check-in, even while an error is unresolved. Responsibility for the filing sits with the property's account holder (RD 933/2021) — don't wait for it to fix itself if the error isn't one of the automatic ones.
Frequently asked questions
Do I need to do anything when I see "Partial errors" on a reservation?+
It depends on the error. If it's one BookCheckin fixes automatically (duplicates, blank guest slots, country-code format, surname particles), it gets resubmitted on its own on the next cycle. For everything else — like a postal code — you need to fix the data and resubmit yourself, following the steps in this manual.
What's the difference between "Partial errors" and "Rejected"?+
"Partial errors" means the Ministry accepted part of the reservation but rejected one or more specific guests — the rest is already registered. "Rejected" means the whole submission bounced. Either way, the text next to each guest tells you exactly what went wrong.
Can I edit a guest's data directly once it's been submitted?+
Not from the reservation page — SES Hospedajes has no edit operation, only cancel and re-file. That's why correcting it means cancelling, using Re-collect or Remove, and resubmitting.
If I fix the error after the 24-hour window, do I still have a legal problem?+
Yes. The 24-hour deadline from the guest's check-in doesn't pause because there's a pending error — responsibility for filing on time sits with the property's account holder, under RD 933/2021. Fix it and resubmit as soon as you can.
