Getting Data In

How do you use extracted JSON fields in transactions and buckets?

I tried doing the following and got back nothing:
sourcetype=json | transaction 'LogEntry.Content.SvctagSegmentGrp.DpsNum'

but had no results. However, when I do the following, I get the expected results:
sourcetype=json | eval DispatchNumber='LogEntry.Content.SvctagSegmentGrp.DpsNum' | transaction DispatchNumber

Has anyone encountered this issue?

Remove the single-quotes from your field name:

sourcetype=json | transaction LogEntry.Content.SvctagSegmentGrp.DpsNum

OK, that worked for transaction, but when I do something like strptime, I need the single quotes. Is there some scorecard indicating when and when not?
eval TimeOpen = now() - strptime(LogEntry.Content.StatusSegmentGrp.StatusDate, "%a %b %d %H:%M:%S %Z %Y") - Does not Work
eval TimeOpen = now() - strptime('LogEntry.Content.StatusSegmentGrp.StatusDate', "%a %b %d %H:%M:%S %Z %Y") - Works

transaction LogEntry.Content.StatusSegmentGrp.StatusDate - Works
transaction 'LogEntry.Content.StatusSegmentGrp.StatusDate' - Does not Work

Based on your two scenarios, it would appear that you need them when you're passing the field name to an eval function (like strptime), but not in the case where it's just an argument to a command (like transaction).

I would have thought so as well, however, when passing a field to a macro it only works with no single quotes. I think that there really needs to be a scorecard or some uniformity.

...many years later... I thought I would just add, I've seen similar symptoms, renaming your field before using it in eval and I believe a few other commands will keep it consistent for you.
