Changing an article's unit for subdivision - intermediary thoughts (with relationship diagrams)

[wvengen]

Hi,

I'm rethinking the subdivision approach, and I'd like to give you the
opportunity to be involved in the process (disclaimer: I'm not finished
in the thinking process). Please find attached a partial relationship
diagram showing how suppliers, articles and orders are related.

Goal is to improve a foodcoop distributing in different units than what
the supplier provides (e.g. foodcoop distributes per liter, supplier
provides juice per 10 packs of 15ltr). Currently this can be done by
adapting the unit, then on next sharedlists sync the price and
unit_quantity is updated.

Best,
- Willem


p.s. the xml files are for use with https://draw.io/

p.p.s. the Draper approach almost worked, but became too complicated
with the decorated associations that were needed.
