One common thing you will encounter throughout the Inventory functions is the "Lens Filter". The "Lens Filter" is a window where you setup the information for your search criteria:
For example you could setup the "Lens Filter" to report on only a certain Vendor or a combination of Manufacturer and Lens Styles or any other specified field combination.
To see the field item selection list, just click on the 
button beside that field.
For example, let say you want to run the "Inventory Breakage Report" for:
- Manufaturer: "SILO" (Essilor)
- Lens Style: "SV" (Single Vision)
- Pre-Treatment: "PLC" (Polarized with SRC)
You would setup your "Lens Filter" like this:
Once you are happy with your selections, click on the 
button.
Next example: Let's keep the same criteria but now just for "Finished" lenses; you would select "Finished" from the "Type" field:
Once you are happy with your selections, click on the button.
Next example: Keep the same criteria but you want to select all the colors between "Brown 3" and "Gray 3":
Once you are happy with your selections, click on the button.
But for any reason you just don't want to keep these selections and you just want to exit out of the "Lens Filter", click on the exit 
button.
