Set up data mappings for a Clintrial subset

1. Create a data set for the grouping panel that contains the subset, and:
   • In the Custom Data Dimensions section of the Data Set Properties dialog box, add a custom data dimension for the subset key item.

     The name of the custom data dimension becomes the name of the subset key item in the data mappings and in the Clintrial panel. This name must not be the same as the RefName or alias of any data series in the data set.

   • In the Custom Dimension Labels - Select Codelist dialog box, select or create a codelist that has a codelist item label for each value that the subset key item can have.
2. Create a data series for each item in the subset.
3. Add the items that participate in the subset to the appropriate data series.
4. In the Select Custom Dimension dialog box for each item:
   1. Select the custom data dimension you created for the subset key item.
   2. In the Labels column, select the label that corresponds to the subset key item value with which the item will be stored in Clintrial.
   3. Click OK.
