General concept of the FSM feature
Person reservations in FSM can be set as either exclusive or not exclusive. Non-exclusive reservations can overlap with other reservations and activities. An exclusive reservation (striped) makes it impossible for assignments to be dropped onto the employee's schedule because the person is reserved solely for the business partner.
FSM Cloud Connector features
If the ‘non-exclusive’ field in transaction /PACG/ECM_T554S – Attendance and Absence Types for connector is set, the person reservation is sent as non-exclusive to FSM. By default the checkbox is left unchecked.
