Data mapping setup for referencing specific instances of an item

If an item that you will use in a rule appears multiple times in a study, you can use either of the following approaches to setting up a data mapping so that you can reference specific instances of the item:

• When you add an item to a data series in the Data Series Summary tab of the Form or Study Event editor, specify the instances of the item that you want to be mapped to the data series.
• When you create a data set, select standard data dimensions that enable the data set methods you need in the Data Mappings tab.
