Enter 2L. The default value for Search Type is Partial Match at Beginning. Leave this setting because we want all items that have a 2L at the beginning of the description.
Click Non-matching records. This will tell the system to ignore(or take out of the filter) any items that match the UPC number we entered above. This feature gives you way to say "ignore these items".
When our filter is complete, you will end up with a list that has all items that have 2L as the start of the Description and amy items that have a UPC that starts with 0490 have been removed from the list.
