Trying to save a Journal Entry and receiving 'Transaction was not complete.' Has anyone ran into a similar issue that can shed some light on if it is a suitescript error or a data error?

I don't recall that specific error, but you need to make sure both debits/credits lines exist and they balance.

They do match fortunately. Wish they'd give a little more detail as to why.

Is it possible that there is a transaction body field that isn't getting populated?
