SQL Report not Working

Question

We have this DCM report in SCCM 2007 and we want to migrate it to SCCM 2012. In SCCM 2007, this report is working when you run it in the sccm console, but does not work when you run it in sql management studio. The error that I am encountering in sql management
studio is
The EXECUTE permission was denied on the object 'fnBuildCICategories', database 'SMS_ABC', schema 'dbo'
After importing this report in SCCM 2012, this report is giving me the same error when running from the sccm console as well as in sql management studio
Can anyone help me resolve this issue. Here is the sql report
declare
@severity varchar(255)
declare
@cicontentversion varchar(255)
declare
@name varchar(255)
declare
@category varchar(255)
set
@severity =

@name =

set
@cicontentversion =

@category =

if
IsNumeric(@severity)<>1
begin
select @severity=Severity
from v_CIValidationSeverity
where
Description=@severity

I bet you have an SSRS exestuation account that has been given the correct permission within the CM12 db. Are you dbo for CM12 db? if not have you grant yourself db_reader and sms_report reader (local group) rights?
Did you know that even if you do that this working, there is another issue with respect to converting varchar to int?
