Ver.13.1.0 Multi-user simultaneous schedule : Exclusive control for each right to edit and object

An exclusive control function that prevents simultaneous editing of the same object by multiple planners when a schedule is edited by multiple persons has been added. To edit an object, the planner must first reserve the right to edit. If the right to edit is acquired by another user first, the planner must wait for the editing by that user to end. The planner can now know in real time who is editing objects.
* Ver. 1.0.0.44 or later Asprova NLS/DS is required.
