I notice that a few create methods allow for passing an existing reference to update an existing item, but it doesn’t appear that this is possible for Journals. Am I missing something? It returns a “JournalReference” when a Journal is created, so an external system could store that and use to update the the journal if the method supported it.
As an aside, you have to look at each method’s documentation to see whether update is possible; it would be better if the description for create methods that support this said something like “Create a new journal or update an existing journal”
Thanks
