Use specific settings on item coverage

Hi,

In AX 2012, from Released product → Item coverage → General tab, there is a checkbox called “Use specific settings”. What is this used for?

Thanks,

The coverage group assigned to the item has a default vendor as well as the coverage group. At this level you are defining the settings per site/warehouse, and if you tick the “use specific settings” you can alter the default coverage group and vendor for this site/warehouse.
