How are study objects that are part of a data mapping copied?

The following table explains how study objects are copied when they are part of a data mapping. You can copy study objects from a library to a study or another library as well as from a study to another study. You also can copy study objects in the Project Explorer.

When you copy a data mapping, data set, or data series within a study or library, the new study object contains item mappings.

Implications of copying study objects in data mappings

Copied study object	Copied within a study or library	Copied from one study or library to another
Data mapping, data set, or data series	Mappings to items that are part of the data series are retained in the new study object.	Item mappings are not copied to the new study object.
Item, Form, or study event that is mapped to a data series	The new study object is mapped to the data series. If you break the link between the original and the new study object, the new study object is still mapped to the data series.	The study object is copied, but data mappings are not copied. Note: If you drag and drop a study object that is mapped to a data series, and the study object already exists in the library, the database contains a data point for the study object, and the drop operation reuses that data point as is. The application warns you that the drag and drop operation is not supported. If you continue, any data mappings in the dropped study object that are different from the data mappings that are associated with the study object that already exists in the library are removed.

Copied study object

Copied within a study or library

Copied from one study or library to another

Data mapping, data set, or data series

Mappings to items that are part of the data series are retained in the new study object.

Item mappings are not copied to the new study object.

Item, Form, or study event that is mapped to a data series

The new study object is mapped to the data series.

If you break the link between the original and the new study object, the new study object is still mapped to the data series.

The study object is copied, but data mappings are not copied.

Note: If you drag and drop a study object that is mapped to a data series, and the study object already exists in the library, the database contains a data point for the study object, and the drop operation reuses that data point as is. The application warns you that the drag and drop operation is not supported. If you continue, any data mappings in the dropped study object that are different from the data mappings that are associated with the study object that already exists in the library are removed.

Note: When a data series is copied within a study or library, the items that are part of a data series are not copied, but data series mappings to items are copied. For example, if an item is added to a data series, and the item is mapped to be part of the data series only when the item appears in a specific form, the mapping of the item to the data series for the form is copied. Similarly, if you copy a data set or mapping definition containing a data series, the mappings are also copied. If you use the new data series in another study, the mappings are retained. If you later add the item and form that are mapped to the data series to the study containing the data series, the mapping appears in the Data Series Summary tab.
