I have been trying to figure this out for a few hours now and am not figuring it out. I'm sure there is some simple way to do it, but haven't gotten it yet. I am trying to create a chart of job streams to know when a complete stream starts and finishes. I don't care necessarily what happens in the middle just when the chain starts and ends so we can compare this on a daily basis. Right now I have been able to separate out the first job in the stream and the last job in the stream and when they start and finish each. What I am having trouble doing is joining them together to complete the picture. There is no fields to join on. If I could come up with a Run Number field, I could join on that plus the combination of the date and job stream name. Basically I need the yellow column below. How could I go about that? A count that starts over based on date and job stream name.
