Hi,
This thread is from 6 years ago, ideally you would have created a new question and could have tagged me in it, but in any case. The fields aren't being set because you're using "outGr" and trying to get the value of it, but that is your brand new initialized record. If your BR is on Incident, and you're trying to get values from that record, then you'd need to use "current" instead. So current.getvalue('field_a'), etc.
You also shouldn't use current.update() in your BR either. So if this is a before BR, then it'll update the task_number field by itself.
Please consider marking my reply as Helpful and/or Accept Solution, if applicable. Thanks!
