Currently you can create a change based alert on the IBAN field of a vendor but that alert only applies for that single vendor and not all vendors. I have found a way by creating this alert via the SysTableBrowser but the only downside is that the system doesn't notify which account has been changed and there is no link which will redirect you to it.

This has been defined as "Working as designed", therefore it would be in our best interest if we could create a change based alert on the IBAN field, that applies to all vendors.
