Mapping associated forms to a CDD

The target table for an association has a fixed format that consists of ID and index columns to identify the visit instance, form instance, and patient for the data in the two associated forms. Instead of specifying data sets and data series for the data in each form, you specify the association.

1. Create two repeating, common forms, and associate them.
2. Create a data set.

   Note: Do not create any data series in the data set. You can create mappings for associations only in a data set that has no data series.

3. In the Properties Browser, select the associated forms as the value of the Associated Forms property, and press Enter.

Note: If you change the association between two forms, you must manually update the data mapping by changing the value of the Associated Forms CDD custom property of the data set.
