Persistence of data mappings

After you add an item to a data series in a data mapping, the association between the item and data mapping persists wherever the item and data mappings are used. Therefore, you can create a data mapping between an item and a data series once and never have to recreate it in other studies.

Even when a mapped item and data mapping are not used together in a study, the association still exists. If you use the data mapping in another study and later add the item to the study, the item's mapping to the data mapping is restored. Similarly, the data mapping is restored if a study contains an item and the data mapping is later added to the library.
