Why is the "Invoice Messaging" field cleared when Tax is calculated?


When selecting 'Calculate Sales Tax' button on the Quote object, the "Invoice Messaging" (AVA_SFQUOTES_Invoice_Messaging_c) is cleared out.




  • "Invoice Messaging" field is used for VAT calculations only.
    • When text is manually entered in this field with US addresses and tax calculation is performed, AvaTax for Salesforce does not receive any response from the service for this field, so it will be overwritten by blank value.
  • This field is specifically used by Avalara and data will be populated for EU countries addresses only.
