Thanks Nicolas,
This far it's well understood:
if "Update the product stock on invoice order status" = Yes, then it's whatever "Invoice order statuses" are.
Still leaves one - no, meanwhile two - questions open:
- Say I have "Invoice order statuses" set to only "confirmed" (because that's when I want the invoice issued), but I want the product stock updated at a 'later' order status named "paid" (because I want the product stock updated only then, not sooner), what do I do to make that happen?
- If I add both "confirmed" and "paid" to "Invoice order statuses" as you're suggesting: do I then have (PDF) invoices issued and/or going out twice, and stock updated twice too?
Admittedly, I haven't tried it out. But you see, it's not clear, neither from option field names, nor from documentation... or, unfortunately, even from your posts here... but it would be nice if it were clear, of course.
So, thanks in advance for making it clear - here, and best also in documentation and backend field/option titles.
