We have a similar situation. We have approximately 10,000 items in our list that need a price change but they are all different prices so the copy and paste feature does not work.  Additionally, they are not changing by a uniform amount (eg, some may change 2.3% and others may change 7.9% and so on). All the correct data is in an excel spreadsheet which I could import by copying and pasting but that would override my quantities on hand, on order or WIP fields.  Please advise.
