There might be a reason for not continuing under a PM program, for example if the object is close to being decommissioned and needs to have its individual set of actions for the remainder of its life. This process will disconnect an object from a PM program. When disconnecting from a PM program, it is possible to decide if PM Actions should be removed or kept as is. In either scenarios, the connection between PM program and the PM actions will be removed and the detail on PM program will be cleared from both PM Actions and the corresponding object.
It is possible to perform this function on multiple objects, as a Background job.
