Hello,

In Odoo 18 SaaS, the bank statement reconciliation behavior has changed compared to v15. Automatic propagation of corrections across related bank statements is no longer handled the same way by default.

Since SaaS environments have limited customization access, there is no direct configuration available to fully restore the exact v15 behavior. In most cases, related statement corrections now need to be adjusted manually or through a customized reconciliation workflow.

You may want to review your reconciliation process or consider automation through custom development if this is a frequent requirement.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.

Odoo changed how bank statements work starting in v16. In v15, correcting one statement could update others automatically, but in v18 each statement line is independent, so corrections don’t propagate anymore. Unfortunately, this behavior can’t be switched back in SaaS.

What you can do is rely more on Reconciliation Models, so Odoo applies the right rules automatically and you don’t have to repeat the same correction on every statement. Another option is using Undo Reconciliation on a wrong match so Odoo proposes the correct one again.

If you ever move to Odoo.sh or On‑Premise, a small custom module could restore the old behavior — but on SaaS it’s not possible.

Hope this helps you move forward.
