May be this:
WITH t AS
        (SELECT 1 id, 'A' str FROM DUAL
         UNION ALL
         SELECT 1, 'B' FROM DUAL
         UNION ALL
         SELECT 2, 'F' FROM DUAL
         UNION ALL
         SELECT 2, 'F' FROM DUAL
         UNION ALL
         SELECT 3, 'C' FROM DUAL
         UNION ALL
         SELECT 4, 'D' FROM DUAL
         UNION ALL
         SELECT 4, 'E' FROM DUAL),
     t1 AS
        (SELECT id,
                CASE
                   WHEN COUNT (DISTINCT str) OVER (PARTITION BY id) > 1 THEN
                      'MULTIPLE'
                   ELSE
                      str
                END
                   str
           FROM t)
  SELECT id, str
    FROM t1
GROUP BY id, str
ORDER BY 1;Cheers,
