Scott Gray commented on OFBIZ-5704:
-----------------------------------
It seems the contentious debate here is whether there should be a
manufacturerPartyId on the Lot entity or if we should support the ability to
assign multiple parties in various roles to a Lot using a new LotRole entity.
There is nothing inherently wrong with using a manufacturerPartyId field if
that is all that the currently known requirements dictate. The reason not to
is because the data model is a pain to change if we later decide we need to be
able to assign more parties to a Lot.
So my opinion is that unless we know of a use case for multiple party
assignment to Lots then we should use Pierre's single party assignment
approach. If we do know of a use case for multi party assignment to Lots then
I agree with Adrian the a LotRole entity would make more sense. But without
known use cases we can't even be sure that a LotRole entity would fill a useful
need when there's the possibility that each party assignment would require
different supplementary data and thus require a completely different data model
design.
Adrian, IMO it is not fair to disagree and claim a design flawed without at
least providing a real world use case (even if only hypothetical) that the
design fails to accommodate.
tldr: If we don't have a use case for multiple parties then let's use Pierre's
approach.

>
> Rationale
> Lot or batch management affects two places, namely the outbound process (and
> its functionalities) and inbound.
> It is possible that multiple parties have the same ID for the batch or the
> lot. Howver, in current feature set there is no discrimination between lots
> from supplier A, supplier B, or even the primary (internal) company in OFBiz.
> Therefore the entity 'Lot' should be extended with another key, namely that
> of the partyId of the manufacturer (or supplier).
