A cumulative sum that resets based on an event?
I'm trying to find a relationship between uses and part lifetime. This is a part that runs constantly when in use. I need a running total that resets when the part is replaced. In my case, I have the first four columns, I want to know how to create the "Jobs Part has Done" column that resets when a Repair event is detected.DateTime StartedDateTime EndedJobsEventJobs Part has Done1/1/2019 8:00 AM1/...
