MIRO Balance not zero verification not working

Hello,

During Invoice Verification, I can post an invoice with negative balance.

I know there is an standar error message called M8534 "Balance not zero: &  debits: &  credits: &"; this is a system setting to control the MIRO.

But in my case, seems that this messagge isn't working.

Any ideas how solve this?

Thanks a lot.
