I would like to have an option to prioritize one source system above another source system so that a person from the primary system ALWAYS becomes the primary person in case of (automatic) aggregation. This is especially the case when the secondary source system is only being used for source enrichment. Since person data in the source enrichment source systems is obviously not complete since it is not (really) an HR system (e.g. Student Information System like Somtoday or Magister), accounts cannot and must not be created from data from secondary systems. It must be prevented to do so at all times to prevent errors in HelloID and target systems.
