   requestBody:
     description: |-
       The request is designed to set the status of several patients, specified by patId (mensId) or BSN, at once. The endpoint is idempotent for the combination of careprogram, callUpStatus and BSN or patId. That means that the call-up status for a patient in a certain care program is just set once, until a new status is set. As a consequence only the employee who set first a certain status is stored, until somebody else (or the same employee) overwrites the status.
