Field help (SSTENTCOD) 

Enter the Entity/use code to calculate the precise tax amount for the customer. This tax code is compatible with the Avalara system and makes it possible to determine the customer type for fiscal purposes.

This field is available for all countries. The Entity/Use code can be entered for any delivery address when a document is being processed for a country that is tax-exempt. When the Calculate alldocuments connection with SST is set to No andan Entity/use code is entered, the document is exempt from tax and not subject to processing costs.
