Click Manage Inventory/Counts
Click Select Locations box
Choose the location and all the products in that location will be listed.
You CAN remove any products that DO NOT have transactions associated with them. These will have a red box with a minus sign.
If a product has an N/A next to it then it has historical transactions and CANNOT be deleted from this location. You CAN delete any counts associated with this product. That will destroy any historical data. But if that's OK with you then delete the counts and then you can remove this product from this location!
