How to Cancel Your Slow User Transactions
Problem
From time to time there is a transaction that does not return, and blocks your other transactions.
The platform has a built-in method that allows the user running that transaction to kill it.
Solution
When this happens, have your users paste this address into any browser tab:
https://<INSTANCE>.service-now.com/cancel_my_transaction.do
and hit the enter/return key. In most cases, this kills the active transaction.
If this does not work, contact your ServiceNow admin team and they can kill the transaction on that active node.
