This tab is used to define a whole country as a zone, for example, if a price sheet lists a set price to Denmark, no matter where in the country it is being delivered to.

Zone column

The "Zone" column is the name you give to the specific country zone and will be referenced later. If each country is in a different price zone, then you could simply name the zones as the following: ZoneDE for Germany, ZoneDK for Denmark, and so on.

Country_ISOA2 column

The ISOA2 code is used to reference the specific countries in the system. DK for Denmark, DE for Germany etc. 

If several countries are in the same zone, then you could simply name them Zone_01, Zone_02 as in the below example.
