Regarding Invoice Groups, is it possible via email.send to “attach” the email under the Communications tab to the record?

transactionId

does not work in this situation, because it’s not treated as a transaction. I know it is possible when done via Workflow, or in the UI, but we need to be in script context.

should probably ask again in #C29HQS63G

😆 didn’t even realize I was in this channel. I heard from someone else that NS Support said this is not supported at this time. Invoice Groups are definitely an interesting animal. Thanks @David B
