  Quick question.  If you are filtering by  a.StateName in ('Submitted','Assign To') then how do got  Processdate='9/27/18 15:16' as it coming under a.StateName in ('Resolved','Acknowledge')

  When you post sample data, you'll get a whole lot better help if you post it in a readily consumable format as code.  Please see the first link in my signature below for how to do that.

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.

  This query has a bunch of errors.  You reference an alias 'b' that is never defined.  You have conditional expressions, but no WHERE clause.
