Include and exclude sets
It is important to understand the distinction between qualifications sets and include or exclude sets. Qualifications are used to narrow the CIs in the baseline or target to a given subset of CIs instances. These instances reflect the classes and attributes you specified in the qualification set and are later compared using a comparison job.
Include and exclude sets apply only to CI attributes. Includes and excludes allow you to specify the attributes that should be included or excluded, thus filtering the number of attributes that are to be considered for comparison when the comparison job runs.
