Depending on your workflow requirements, you may not need to use some of these Asset Handling modules. If, for example, you are not using services from a prepress service provider and do not have access to an OPI server, you should deactivate the OPI System Support. Deactivating modules which are not needed for your specific workflow enhances productivity by freeing up Cumulus’ resources and speeding up the cataloging process. To meet individual workflow requirements Asset Storage, Asset Processor and Metadata modules can be activated and deactivated for each Asset Handling Set individually. Note that you need the appropriate permissions to change Asset Handling Sets.
To activate or deactivate an Asset Handling module for an Asset Handling Set:
1. Launch your Cumulus application and open any one catalog.
2. Select Cumulus / Edit > Preferences.
3. Click Asset Handling Sets.
4. Under Set, select the set you want to edit.
5. Click Modules and select the icon for the module type.
6. Select the desired module and click Activate /Deactivate.
7. Click Apply or OK to save your changes.
Now the module is (de)activated for the selected Asset Handling Set.
