Error: During 'Validating that Tax Code '' exists in Dynamics 365':
ConnectWise Tax Code '' could not be found in Dynamics 365 as a Tax Area
Resolution: This typically means that there's no tax code in the CW invoice data.
This functionality is part of our middleware functionality that all the .NET integrations inherit. There needs to be a tax code put on the ConnectWise invoice even if it is not taxable. In cases if it's not taxable please put Tax Exempt tax code.
