How to identify & Abort a Teradata session.

We have to drop/recreate a JI as part of our daily batch cycle.. sometimes, we run into a locking issue because BI users were still on the system locking the JI.
I'm looking for a way to identify those sessions who holding any locks on the JI and its underlying tables, and then kill/abort those sessions before we start to drop/recreate those JIs.

Does anyone know how to do this?

Thanks
