When creating a new Calibration session or if a session is already created, we can find "Session Owners" field is mandatory.
Performance Management, Calibration, Reporting, Analytics.
Reproducing the Issue
If you open an already created Calibration Session or when create a New Clibration Session, we have a field "Session Owners" which has been changed to Mandatory Field.
This Enhancement was done because when a session has no Session Owner, then the Session would not display in report if the Session Owner field is selected.
If owner does not exist, the whole result cannot be retrieved. Also it would not be right to have a Session without session owner.
Hence the Session Owner is made as required field for a calibration session in B1511 release. (See attachment)
