The error message below is displayed by the Support Debugging Tool when setting up the SQL Profile Tracing functionality from the Administrator Settings >> SQL Profile Trace Settings window:
An error occurred executing SQL statements: MBS_Grant_IMPERSONATE. GPS Error: 24, SQL Error: 15151 [Microsoft][SQL Server Native Client 10.0][SQL Server]Cannot fine the login ‘XXX’, because it does not exist or you do not have permission.
This error will occur if there are user records in the SY_Users_MSTR (SY01400) table which do not have an associated SQL Login at the SQL Server. If you capture a DEXSQL.LOG, you will be able to see the user(s) that are causing the issue. For example:
/* Date: 09/19/2012 Time: 21:33:45
SQLSTATE:(37000) Native Err:(15151) stmt(45087392):*/
[Microsoft][SQL Server Native Client 10.0][SQL Server]Cannot find the login ‘XXX‘, because it does not exist or you do not have permission.*/
To resolve this issue either create the missing SQL Logins or remove the additional Microsoft Dynamics GP users from the system, so that SQL and the SY01400 table match.
