Why current.update() Is Breaking Your ServiceNow Implementation (And You Don’t Realize It)

Recently, I ran into a strange issue in ServiceNow — for a single update, the system was sending duplicate notifications . At first, it looked like a notification configuration problem, but after digging deeper, the real culprit was unexpected: multiple current.update() calls triggering the same logic repeatedly. This wasn’t just a one-off mistake — I’ve seen this pattern quite often, where developers use current.update() without fully understanding its impact.
