Filtering your items allows you select a group of items, and any item not in the filter will be hidden from view. Filters stay on until you clear the filter or you leave the Pricebook. You can tell if your grid is filtered by looking at the bottom of the My Pricebook window. Filters will be used for doing things in a batch. The most common use will be to do group price changes.
You can build a Filter using one or more fields. In this example we are going to create the following filter:
All items with UPC codes that start with 0120(a large beverage Manufacturer) and
Once we selected UPC, UPC is displayed above the Field Value, we enter our info, which is 0120 in this case. The default value for Search Type is Partial Match at Beginning.
The By Range control opens for the Price field automatically. You can enter a range of prices, but in our example we only want items that have a Price of $1.69. so 1.69 is entered in the Starting and Ending Range.
