Using pricing worksheets (BL/DST)
You can use pricing worksheets to precalculate and massage price bases before you actually update them. You can create price bases from worksheet prices by using an existing item price source: issue cost, last received cost, or another base's current base.
When you create a pricing worksheet, you can perform a mass update to apply new prices to items by vendor, major sales class, or item number range.
