Hi Anesu,
If this is the case, I would suggest resequencing, which you can carry out directly in the frontend. Select at least the last invoice or all invoices with the wrong number and then click on “Resequencing” via “Action”. Here you can now enter the sequence that you normally use in the “First new sequence” field. You can also select whether all invoices should receive the new sequence order according to the current sequence or the posting date.

I hope that this already solves your challenge.

Kind regards,
