Filling or Updating the Repository 
Use
The
CCMS system repository is automatically filled with data, and the data is refreshed at irregular intervals. You can also update the system repository manually.Procedure

If a suitable job already has been scheduled and has not run, this job will be used. No extra job will be scheduled to update the repository.
To fill the system repository the first time, the background job runs less than 30 minutes long in all but extremely large or very busy systems. Updating a repository that has already been filled usually takes only a few minutes in the background processing system.
