Here is a report that will show the number of tickets open and closed by quarter.

Looks great if you have it set to brake on year.


SELECT OPEN.QUARTER,
  OPEN.YEAR,
  OPEN.OPEN,
  CLOSED.CLOSED   
  FROM (SELECT CASE
WHEN MONTH(T.CREATED) < 4 THEN  'Q1'
WHEN MONTH(T.CREATED) < 7 THEN  'Q2'
WHEN MONTH(T.CREATED) < 10 THEN  'Q3'
ELSE 'Q4'
  END AS 'QUARTER',
  YEAR (T.CREATED) AS YEAR,
              COUNT(*) AS OPEN
FROM HD_TICKET T
GROUP BY QUARTER,
YEAR
ORDER BY YEAR,
QUARTER) OPEN,
(SELECT CASE
          WHEN MONTH(T.TIME_CLOSED) < 4 THEN  'Q1'
          WHEN MONTH(T.TIME_CLOSED) < 7 THEN  'Q2'
          WHEN MONTH(T.TIME_CLOSED) < 10 THEN  'Q3'
          ELSE 'Q4'
  END AS 'QUARTER',
  YEAR (T.TIME_CLOSED) AS YEAR,
  COUNT(*) AS CLOSED
FROM HD_TICKET T
WHERE T.TIME_CLOSED NOT LIKE '0000%'
GROUP BY QUARTER,
YEAR
ORDER BY YEAR,
QUARTER) CLOSED
WHERE OPEN.QUARTER = CLOSED.QUARTER
  AND OPEN.YEAR = CLOSED.YEAR
