Constraint Error

Invoice Number must be unique per Company!

From what I can see, the invoice number is unique.

I have the same problem since today.

I'm receiving the same error when I validate a vendor bill in Odoo 10. Does anybody know how how to fix it?

In version 11 go to Accounting->Configuration->Accounting->Journals and select the document type.  Then under the "Journal Entries" tab you should be able to increase the "Next number" so it's not a duplicate. 


Check Vendor Bills -> Other Info -> Journal -> Entry sequence.
