If in every trial, you can choose any of the response profiles, you can omit the Profile ID Choices selection under Pick Role Variables in the Response Data section of the Choice launch window. The Choice Model platform then assumes that all choice profiles are available on each run.

If you have subject data in the Response data table, select this table as the Select Data Table under the Subject Data. In this case, a Subject ID column does not need to be specified. In fact, it is not used. It is generally assumed that the subject data repeats consistently in multiple runs for each subject.
