AnterraDataCenter synchronizations are run by Windows Server Scheduled Tasks. 

Navigate to C:\Windows\System32\Tasks on the server. You will see a list of all of the tasks if a local administrator.

Right-click the scheduled task and choose Permissions. Add the user or group that you want to give access to the task. Only Read and Execute are required to run the scheduled task.

Users will now be able to see the scheduled task in the Task Scheduler. Right-click and select Run to execute the task.  Tasks are typically named to tell you what the synchronization does - for example the task might be called - Sage to SQL Update, GL Update, AnterraBI Full Update.  Running the task will synchronize data between Sage and SQL and SQL and AnterraBI.
