Can we handle different units of measure for the purchase unit of an item? (i.e. for different vendors on an item) Example: We have item XYZ and 2 vendors sell it to us. Vendor A sells in packs of 20 at $100 and Vendor B sells in packs of 10 at $60. So both the unit and the price are different. Do we just set purchase units based on preferred vendor and manually adjust for the other vendor on purchase transactions?
