I need some help interpreting this execution plan - https://www.brentozar.com/pastetheplan/?id=SJ5NYLLSL
Whenever this query is ran it uses up a huge amount of CPU and kills the server.
I have little experience in interpreting execution and am not sure what to look at/suggest to improve. I notice the amount of left joins and the size of some of the tables and would suggest adding an index somewhere but am unsure on what table and what fields. Thanks.
