How to resolve the error: "The AVA Detail History already exists"?


I get the following AvaTax error when I post invoices in Microsoft Dynamics NAV 2009 R2:

"The AVA Detail History already exists

Identification fields and values:

Tax Header No. = xxx, Tax Line Id =x, tax Detail = x"


Microsoft Dynamics NAV 2009 R2


  • Update connector build to Avalara AvaTax for Microsoft Dynamics NAV 2009 R2 - 6.00.32012.18.00 or later

Note: AvaTax for Microsoft Dynamics NAV 2009 has been sunsetted and is no longer supported by Avalara as of April 30, 2016. This existing knowledge base documentation is available to provide known paths to resolution for documented issues. If you are using a version affected by service discontinuation and want to maintain access to Avalara Support, you’ll need to upgrade to the latest version of the integration as soon as possible
