Schedule spans are created without the associated schedule.Issue We have created a new schedule page on Maintenance Windows and Changes schedule page. There seems to be a defect on the calendar. When you double-click empty space inside the calendar cell, Add Schedule Item popup gets displayed. When you fill in the fields and save, it will create a new Schedule entry, but the problem is it inserts invalid data. ResolutionThe behavior seen is expected per out of box behavior. If the module users click do not pass the schedule sys_id in the URL, the schedule entry will not have a default value for the 'Schedule' field. One suggestion is to add the 'Schedule' field to the 'default' view on the schedule entry form. This field will then reflect in the 'Add Schedule Item' pop-up found in the calendar UI. When users add a new schedule item, they can set the Schedule value here.
