We would like to get notification if some specific account information (e.g. Sales Person/ Sales Branch, Tax Registration ID, etc) has been modified.
Currently it is only possible to add a MESSAGE handler to the event
Account Information Updated, the notification will be sent on any information update on the account (without specifying what exactly has been changed).
For tax registration ID change a feature request #PBA-64331 ("Notify provider on customer's Tax Registration ID change") exists.
