Before implementing Vertex in QAD EE, it is important to understand how business relation data is stored. Business relations provide a single point of entry for address data that you can then use in multiple places in the system.
Business relations function at the database or system level, and are visible to all domains, unless you set the Domain Restricted field to Yes on the General settings tab in the Business Relation Create screen.
In addition to address data, business relations store tax data. If you create a business relation in a domain with Vertex, Vertex assigns a valid Quantum GeoCode to the Tax Zone field of the business relation. If you then use the business relation to create either a supplier or customer record in a shared set in a non-Vertex domain, it is important to adjust the tax zone settings on the customer or supplier record accordingly.
Similarly, if you create a business relation in a non-Vertex domain, the Tax Zone field is not assigned a Quantum GeoCode. If you then use the business relation to create a customer or supplier in a shared set in a Vertex-enabled domain, you must run the Vertex Tax Zone Update Utility to update the tax zone on the customer or supplier record with a Quantum GeoCode.
