#C29HKGM6J #C298P0BCK How do you unapply a journal from a Invoice or credit memo. The journal is not in a closed period, it is not locked by a workflow or script. But when editing you cannot change any values on it??

Hit edit and then save it again without making any changes. that should to it. At least it used to be the case that saving a JE record applied to something, even if you don't make any changes, unapplies anything from it.
