Not a good assumption here.

This is how I distinguished discrete to bulk items. Discrete meant
'discretely identifyable' eg had a unique 'serial number', or could be
assigned a 'stock number'. Items were thus uniquely traceable. Generally
any business selling goods with warranties needs this.
Ok, but then you have to enter every serial number at time of
purchase. I would actually like to support this tracking as an
option, but have it turned off by default. I.e. if you want to flag a
part as noncomparable then you cannot purchase one without attaching
the serial number to the invoice, one part per line item.
For obvious reasons this is not generally applicable to most
businesses or workflows. Also, there might be times when doing things
this way might actually violate tax laws in various countries, so the
part would need to be truly noncomparable (i.e. like a custom-built
computer, not like a 1GB stick of PC2700 RAM).
I generally found that non-discrete items could be considered bulk. They
were bought, held and sold in multiples of 1 or more, but the item was
not uniquely identified by the business. If it was it could be handled
as a discrete item instead, and thus tracked. This way of looking at
items itself is not perfect, but I found it workable for everything I
Parts and assemblies are forward and reverse recursive relationships of
items. In other words everything is an item, and can be separately
expressed as a part and/or component of other items.
No argument there, but it is not applicable to most environmnets. I
have added a feature request for the *option* of flagging parts with a
non-comparable flag that would be used to track by serial number, one
to a line item. Again, few businesses are likely to need it, but
those that do are likely to really need it.

Sounds right. Allowances are forecasts, and I guess there are limits to
taxes claimable on forecasts. This is likely to vary from country to
country, and at election time :-).

Yes, using serial numbers etc: Discrete vs bulk items above.
See my points above. If you are arguing for the option of being able
to track noncomparable items, I am all for that. If you are arguing
that such should be the default, I don't see how you are likely to get
people to accept the added data entry involved when there is no
regulatory compliance reason to do so.

A matter of terminology here. I think you are referring to discrete as
meaning 'not part of an assembly, nor broken down.' I was using it as
meaning 'uniquely identifyable'. This shows the need to define terms as
part of requirements analysis/modelling, and before design/coding
No. This is a different problem and has to do with cost and inventory
accounting when assemblies are stocked. It is a limitation of the
current codebase, which is why I said that it was a matter of not
being able to handle it at the moment.
Hope this is clear,
