Report query with multiple selects

Question

On some of my Report Queries (that have multiple selects) it sometimes changes the rowset when I edit the specific SQL.
For example, I have 2 selects in my Report Query andnd when I download the XML my first select’s data goes into <ROWSET1> and my second select’s data goes into <ROWSET2>. I then make my template and everything is good.
But, sometimes when I edit the SQL in the report it changes the ROWSET number of the data so now my first select’s data in ROWSET2. This blows up the report. Is this a bug? Why is it switching the rowsets back and forth?

Answer 1

I'm referring to the Report queries under shared components.
My first query is like this:
select A.emp_id
from tab1 AC4, tab2 AC3, tab3 AC2, tab4 AC1, tab5 A
where A.year = :page_year
and C.FK_SCHOOL IN (SELECT c001
FROM apex_collections AC1
WHERE AC1.collection_name = 'SIS_REPORTS_SCHOOLS')
and nvl(C.ACTIVE,'NONE') IN (SELECT decode(c001,'NONE',nvl(C.ACTIVE,'NONE'),C001)
FROM apex_collections AC2
WHERE AC2.collection_name = 'SIS_REPORTS_ACTIVES')
and nvl(C5.CALENDAR_NO,'NONE') IN (SELECT decode(c001,'NONE',nvl(C5.CALENDAR_NO,'NONE'),C001)
FROM apex_collections AC3
WHERE AC3.collection_name = 'SIS_REPORTS_SCHOOL_CALENDAR_NOS')
and nvl(C10.CLUSTER_CODE,'NONE') IN (SELECT decode(c001,'NONE',nvl(C10.CLUSTER_CODE,'NONE'),C001)
FROM apex_collections AC4
WHERE AC4.collection_name = 'SIS_REPORTS_CLUSTER_CODES')
My second query needs to select the detail info from other tables, but I only want to do it for the (master) records that were returned in the first query.
