Notification Completion and Scheduling Update

Hi,

Suppose that I scheduled a maintenance plan and it created only one maintenance call. Then, by IP10 I created a notification for this call (using the green flag) and I technically complteded the notification using IW22. Does the system automatically creates the next maintenance call. In my case, it did not create, even if I enter IP10 and save it. (But, when I used the 'update scheduling' button, it created the next call) Hence, my maintenance plan has only one maintenance call, which is completed. Is this not proplem to not have any 'on hold' calls?

Regards,
