Delegated user should be automatically assigned the Incident and RITM

[Saaquib2]

I have a requirement if i have delegated someone for a particular duration  , Once RITM and Incident is assigned to me it should automatically update  the Incident and RITM to the delegated user for that particular time period only .

Please suggest how this is feasible if it is possible in ServiceNow.

Thanks in Advance.

Why? If your delegate is supposed to watch your tickets (assignment delegation/notification delegation), the notifications are already send. 

Also: this would be customization (like a flow looking up the delegate record of the assigned_to where 'assignment' is set to true, check if the current date is within the delegation period and set the assigned_to), that will only work if that user is in the same assignment group (at least, if your 'assigned to' is dependent on the assignment group, which it OOB is). You also run the risk of the assigned_to not having the appropriate roles to view the records. In theory the CFO can make the cleaner his delegate.

If it's really a necessary requirement, you can use the flow option I already described.
