Request Last update duration, filter by analyst

[Joyce]

Hi,

I need a report where we can review how long it take for an analyst to respond to a ticket after a customer has put an update. 

So  have time since last ' analyst ' update as a filter.

I have join Request and h_buzz_activities tables, but I can't find a column to filter ' last update by who'

Thanks.

 

Regards,

Joyce
