When right-clicking on a SQL statement in the Top Activity Section in Profiling, if the SQL statement is run by a different user than the user who is running DBO, than the User Mismatch dialog appears, with an example of the following message: “This query was executed by [SOE] and you are currently connected as [system]. We recommend you reconnect as [SOE] to tune the SQL. Would you like to continue anyway?” This message indicates that the statement is being tuned by a user other than the user who originally ran the query, and tables may be missing based on the different schemas. Click OK to run the query, or click Cancel and run tuning under the original user.
