    MAXDOP =1 means disabling the parallelism. That's why SQL Server doesn't consider parallelizing the query.

    That's why I couldn't see that in the execution plan you posted.

    Exactly, but my plan is using MAXDOP =0 ( 24 cores) in my case. Did you notice this?

    Yes. Does the query have any function calls?
