RE: Unit of measure conversions.. -- SYSTEM21

We have a similar problem.  

I think it partly revolves around the problem that you can't define a
unit of measure as a discrete unit.  

For example in the steel industry our purchase units are in Tonnes but
the others are in Sheets.  For us, you can never sell part of a sheet,
it must always be a whole number.  If you could tell it that sheets must
always be a whole number it would help a lot.

We have the same problem when we invoice as well (especially if selling
in sheets and invoicing in Tonnes or vice-versa).
