so our purchasing dept. has asked for help with purchase discounts from vendors based on item quantity. I've set up Vendor Pricing Schedules and this seems to work to getting the proper pricing based on the different item quantities. However, some vendors may require the use of different MPN or vendor item numbers to determine the packaging needs. This lead to a question about using parent/subitem or matrix items. It seems using purchase units types could solve the issue.

We've never used any units types in the past and with many different combos, I imagine this could get out of control.
