Indicates that SQL Server could not produce an execution plan for a query or batch that contained a plan guide. SQL Server attempted to generate an execution plan for this query or batch without applying the plan guide. An invalid plan guide may be the cause of this problem. You can validate the plan guide by using the sys.fn_validate_plan_guide system function.
