Assigned calendar should be visible even if no dates are available from the calendar

Current Situation

• If a calendar contains dates (e.g. from Monday to Wednesday) and is assigned to the run-time setting of a job or order. Then JOC Cockpit throws an error "no dates available", after adding any "Restriction" (which does not come under the dates already assigned to the calendar e.g. Thursday) in the assigned calendar to the job or order. Also, it is not possible to delete the calendar from the run-time setting of a job or order and this calendar is not visible with the job's or order's run-time setting.

Desired Behavior

• The assigned calendar should be visible even if restriction dates do not come under assigned dates in the calendar.
