Before you generate a report based on an offline object set, you may want to synchronize the content between the current network data and the data stored about the objects in the object set.The most efficient way to synchronize content is to set this option during the creation of a scheduled collection, when you are adding object sets. With this method, the process is automatically done each time the scheduled collection is run. For more information, see To set up a scheduled collection.You can also immediately synchronize an offline object set by right-clicking it in the Reporter console and selecting the Synchronize option.
Synchronizing an offline object set may take some time depending on the number of objects that must be resolved.
