For the Zero in stock, I've tried without any success.
What works pretty well is "Physical transaction" (Create > Items / Create > On hand ) option and "includes item with nothing on hand" (Create > On hand)
I was wondering if I'm going to blog in English as well. I've started to translate some of my posts. It's in my todo list :).
By the way, things I shared are mostly things you should know so you won't miss a lot. The last one was about the "Find next" checkbox on Trade agreements.
I did appreciate the "cancel transaction for supplementary item" of your post I haven't try it for now.
