Is there any way at all to edit a Revenue Element record directly? I know you can't do it via the UI normally but I'm interested in any possible way.

That sounds like a question for suiteanalytics channel, sorry I don't know the answer.

You can edit it in the related Revenue Arrangement.

Thanks guys. I know you can edit it in the RA but I was looking for a way to edit the Customer on a Revenue Element directly. Seems like you can't.
