Hi @Robert Russell​ 

You can use dbutils.notebook.getContext.currentRunId in scala notebooks.

Other methods are also available like

dbutils.notebook.getContext.jobGroup

dbutils.notebook.getContext.rootRunId

dbutils.notebook.getContext.tags etc...

You can check out the list of methods available in getContext using the autofill feature 😅 by hitting tab after dbutils.notebook.getContext.

Cheers..
