If you have the same issue as me you are needing a cheat-sheet so you can do imports. If you have a test environment you can add a single line of data starting with a guess and then look at the output. That is how we created ours. Lots of trial and error. It caused a lot of locked up journals and ghost items so always test thouroughly
I have attatched our template which I hope could help.
*edit: ok, mabe I cannot attatch files here
