Hello swapnil,
1. It is not possible to get the tasklist operations to any of the fields of the triggered Notification.
2. When we opted for Notification through plan, the Notification will have the tasklist details (not operations) in the Maintenance Plan tab of the notification.
3. Last but not the least, if you create an Order through this Notification all the package operations will be copied to the Operations tab of the Order. Just try.
