The guidelines are 30 days for dry market and frozen, and 4 days for cooler product, but really you can scan something as far out as your heart desires! We've done 2-3 months in advance for certain things in dry market before, and I like to put certain things in the open coolers into the SDA as soon as they hit the shelf, such as those weird gourmet cheeses we have, because we don't have the time to ever check them, and no one ever buys them either.
