Why am I getting this null in my OBI generated query?

Question

select D1.c1 as c1,
D1.c2 as c2,
D1.c3 as c3,
D1.c4 as c4
from
(select distinct D1.c1 as c1,
cast(NULL as DOUBLE PRECISION ) as c2,
cast(NULL as DOUBLE PRECISION ) as c3,
cast(NULL as DOUBLE PRECISION ) / nullif( cast(NULL as DOUBLE PRECISION ), 0) as c4,
D1.c2 as c5
from
(select distinct T5.plan_name1 as c1,
T5.plan_name as c2
from
(select
decode(r.plan_type, 10, -1, r.plan_id) ods_plan_id,
r.plan_id,
r.plan_description description,
r.plan_type plan_type_id,
m.meaning plan_type,
r.plan_start_date,
r.plan_cutoff_date,
r.plan_completion_date,
r.sr_instance_id,
r.organization_id,
r.plan_run_id,
r.plan_run_name plan_name,
r.plan_run_name plan_name1
from
msc_plan_runs r,
mfg_lookups m
where lookup_type='MSC_SCN_PLAN_TYPES'
and m.lookup_code=r.plan_type
and nvl(r.archive_flag,2)=1
and m.lookup_code not in (5)
) T5
) D1
) D1
order by c1
This is the SQL I get when I run my report. I am not getting values for the last three columns. What is the reason for it. I am getting the SQL as
cast(NULL as DOUBLE PRECISION ) as c2,

Hi ESORBI,
mod100 is correct. This is related to content levels for your star schema inside the business model. I assume these NULL values are measures on a logical fact (?). If so, have you set the levels for all logical table sources correctly on the fact. Do you have LOGICAL complex joins for all Dimension / Fact combinations you are using in the query? Is there a logical PK for each dimension hierarchy you are using?
Investigate these areas to narrow down the issue.
Hope this helps,
Justin
