What this screen lists
Invoices created as drafts and never posted, so they are not accounting documents yet.
Common causes
- The accounting period is locked in Odoo for the invoice date.
- The journal sequence is misconfigured or exhausted.
- A required tax field is missing on the customer, such as the VAT number.
- A zero-value invoice that Odoo refuses to post.
If you have create the invoice as a draft turned on, posting is your job, and invoices sitting here are expected rather than a fault.
How to clear it
Read the Odoo message on the row — it says exactly what is missing. Fix the cause in Odoo or in your settings, then press Retry on the row, or Retry Fix All if the cause is shared across every row.
Check the earlier screen first
If the same order appears on more than one error screen, start with the earliest in the pipeline. Fixing the first step usually clears the ones after it.
