Consider the following scenario:
- You have Microsoft SQL Server 2008 R2, SQL Server 2012, or SQL Server 2014 installed on a computer.
- You use DTA utility (Database Engine Tuning Advisor) to optimize against some workload.
- The workload being analyzed by DTA includes the execution(s) of one or more user-defined functions (UDF).
The issue occurs because of a defect in SQL Server DTA utility.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
