The service item record stores an address for the sold-to customer, or dealer, and the end user customer. When the record is first created and the customer numbers are entered, the address is pulled from the Accounts Receivable Customer Masterfile. You may override the address on the Service Item if you wish. If the address on the Service Item does not match the address found for the customer in the Customer Masterfile, these buttons will appear. You can press the button to read the new address from the Customer Masterfile and set the Service Item record to match.
