The following SQL error was unexpected.

NAV2015, SQL Server2014

Hey,

my users are getting this error recently: "The following SQL error was unexpected. New request is not allowed to start because it should come with valid transaction descriptor".

Google suggests it's a bug in SQL2005 or I need to install .NET Framework 2.0 Service Pack 1. This did not help.

It happens when they change the Variant Code in the sales line table. After they click the error away and try again it doesn't pop up again.

Do you guys have any suggestions?

Thanks!
