Scripting/modifying report field text?

hi,

Is there a way to modify the text returned by a data source key in a report field? Specifically, I would like to truncate the beginning of the source field text (@alarm_journal.source@). It gets kind of long and the leading prov:default:/tag:XXX/WTP/ could be removed so the tag is easier to read. I'm thinking there might be a way via a script data source but unfortunately, I don't know python...

Thanks,
Jason

There are some string manipulation functions available:

Wonderful, "substring" was what I was looking for. Thanks!
