About tuning up your company database
Database Administration automatically performs maintenance tasks to keep your database functioning efficiently. This maintenance takes place according to schedules you create and assign to companies using the tabs under Schedule Nightly Maintenance. For more information about nightly maintenance schedules, see About scheduling nightly maintenance.
You can also use the Tune Up Company Databases utility to run maintenance tasks at other times, whenever you need to. For more information about running maintenance "on demand," see Tuning up a company database.
Note: The Tune Up Company Databases tab shows the last time maintenance was performed for each Sage 100 Contractor company in your SQL Server instance.
