My clients wants to sell Pizza and therefore he purchases olive-oil in different bottle sizes (e.g. sometimes 1.2 l bottles are a good deal, sometimes 1.6. ounce cans are cheaper) so stock get mixed up. I think it is a quite common use case that the sources for a manufacturing process come in in different units and/or presentations. In manufacture --> bill of materials --> add product  I can define product quantities, that for example reduce nicely my tomato product stock, each time a pizza is sold. I could not figure out, how to relate different incoming product presentations or measurement to a unified consumable/source or have something allowing to scan/register as products arrive into stock and have something that joins what belongs together. I had a similar situation in a textile fabric, so would be awesome to have solution for that sourcing problem. I read howto configure UoM for the sales side, but howto integrate that concept for procurement/manufactoring processes?
