Global Attributes in Supplier FBDI

I am using the "SupplierImportTemplate.xlsm" to import new supplier into system and curious to know what is a "Global Attribute" and how is it different from "Attribute1" and so on. I understand the Attribute1 is used to capture additional information but more curious to know on where and how the "Global Attributes" are used. Could some one give me an example and explanation to clearly understand the distinction between both these types of attributes.
