Dear,
This setting is very interesting one. Click on tab "Object list" in maintenance order and assign notification by creating from there it self, so that system adds the notification description as operation and assigns the technical objects of notification for operation.
Example :
Creating maintenance order on one technical object, but adding several objects in tab"Objects"
"Object" list
Now i add one more equipment and notification:
Now you get pop up to create notification if you click on create icon
Now look at operation tab:System will populate same notification description as operation-2
Hope you got an idea by activating the "Assignment of operations to all object list entries active".
Regards,
Pardhu
