I would like to help you but the problem is SAP table , so if we are tallking about Z-Table, then we can try with a dialog, or MT ( SE30 ) with some events.
Anyhow, this called Database Triggers, so it means any change DML ( Update, Delete,Insert ) on a table,then an event will be triggered,
You can refer to this link for more informations, Database Triggers - Tutorials - SAP Library
