Answer 1

use update for select by join

 UPDATE (select NON_CONFORM_ALLOCTABLE
         from FGMULTI 
          JOIN arinvt ar 
          ON  fgmulti.arinvt_id = ar.id 
         WHERE IN_Date = CurrentDate 
         AND ar.Class LIKE 'CP%' 
         OR ar.Class LIKE 'FG%' 
         OR ar.Class LIKE 'IN%' 
         OR ar.Class LIKE 'LA%' 
         OR ar.Class LIKE 'PK%') t
 SET t.NON_CONFORM_ALLOCATABLE = 'Y' 

Answer 2

You can't use a JOIN in Oracle in an UPDATE statement. You can do that using and exists clause:

UPDATE FGMULTI
   SET NON_CONFORM_ALLOCATABLE = 'Y'
 WHERE IN_Date = CurrentDate 
  AND exists (SELECT 1 
              FROM arinvt ar 
              WHERE fgmulti.arinvt_id = ar.id
               AND (ar.Class LIKE 'CP%' 
                 OR ar.Class LIKE 'FG%' 
                 OR ar.Class LIKE 'IN%' 
                 OR ar.Class LIKE 'LA%' 
                 OR ar.Class LIKE 'PK%'));
