Count / sum function in report problem

Question

Hi
In my report i was using this code to output the area code and count the man_suspend records from the Trans_code colum. Like so
SELECT AUN_CODE,
COUNT(*) FROM rr_transaction WHERE trans_code = 'MAN_SUSPEND'
GROUP BY AUN_CODE
AUN_CODE      COUNT(*)
201                   1
202                   1
204                   3But it wasnt outputing the zeros so i tried using the follwoing statements:
select aun_code,sum(case when rr_transaction.trans_code = 'MAN_SUSPEND' then 1 else 0 end)
from rr_transaction
group by aun_code
SELECT AUN_CODE,
count(case when trans_code = 'MAN_SUSPEND' then 1 end)
FROM rr_transaction
GROUP BY AUN_CODE
These two statements do give me the desire output
of :
AUN_CODE      COUNT(*)
200                   0
201                   1
202                   1
204                   3etc
But when i try using these select statments in my data model in Oracle reports it creates the query box with a broken data link icon and wont let me join it to other queries (the aun_code is the primary key)
Im abit stumped why it will work the first select statement but not the other two!??

Much nicer than my paltry attempt.
select iv2.object_type,nvl(object_count,0) object_count
  from
SELECT object_type,
            COUNT(object_id) object_count 
  FROM user_objects
WHERE object_type  in ('TABLE' ,'FUNCTION','INDEX','PACKAGE')
GROUP BY object_type
) iv1
(select distinct object_type
              from user_objects) iv2
           where iv2.object_type = iv1.object_type(+)
