Avoid boilerplate in reports

Question

Hi,
Unfortunately I have to work with Oracle Reports 2.5 and I am having trouble with controlling the report layout.
Here are the two queries in my report
1.
SELECT
     D.DEPT D_DEPT,
     D.DEPT_NAME D_DEPT_NAME,
     C.CLASS C_CLASS,
     S.SUBCLASS S_SUBCLASS
FROM
     CLASS C,
     SUBCLASS S,
     DEPS D
WHERE     
     D.DEPT = 3
AND     C.CLASS = 19
AND     D.DEPT = C.DEPT
AND      C.DEPT = S.DEPT
AND      C.CLASS = S.CLASS
AND      S.SUBCLASS < 20
GROUP BY
     D.DEPT,
     D.DEPT_NAME,     
     C.CLASS,
     S.SUBCLASS
2.
SELECT
     DL.DEPT DL_DEPT,
     DL.CLASS DL_CLASS,
     DL.SUBCLASS DL_SUBCLASS,
     DL.SKU,
     DL.DESC_UP,
     SUPS.SUP_NAME,
     SUM(ISH.UNITS) ISH_UNITS,
     SUM(ISH.SALES) ISH_SALES_RET,
     SUM(ISH.UNITS*ISH.UNIT_COST) ISH_SALES_COST,
     SUM(ISH.SALES -                (ISH.UNIT_COST*ISH.UNITS)) ISH_GM
FROM      
     ITEM_SALES_HIST ISH,
     DESC_LOOK DL,
     SUPS SUPS,
     ITEM_SUPPLIER ISU,
     V_ORG_HIER VOH
WHERE      
     DL.SKU = ISH.ITEM
AND      ISH.YEAR_454 = 2003
AND      ISH.MONTH_454 = 9
AND      VOH.DIST_COMPANY IN (1,4)
AND      VOH.STORE = ISH.STORE
AND      SUPS.SUPPLIER = ISU.SUPPLIER
AND      ISU.ITEM = DL.SKU
AND      SUPS.VENDOR_GROUP ='UCS'
AND ISH.ITEM IN (40407344,40956266,41782356,41883867)
AND DL.SKU IS NOT NULL
GROUP BY
     DL.DEPT,
     DL.CLASS,
     DL.SUBCLASS,
     DL.SKU,
     DL.DESC_UP,
     SUPS.SUP_NAME
HAVING SUM(ISH.SALES) <> 0
ORDER BY 8 DESC
When I run this report I am getting a page with Dept and Class even if there are no subclasses (detail) found. I only want to show pages with details. Can anyone help me to solve this problem?
Thank you!

Hi Mohan,
I couldn't get rid of the Dept and Class headers with an empty pageYou can try this:
1. Create a summary column in the data model inside the dept group. Choose function > Count and source > subclass, and reset at > dept_group
2. Go to the Dept repeating frame, and in the property inspector > format trigger, write the code in my previous post. Instead of <subclass> write the <summary_column>. Or, you could also use the conditional formatting UI (select hide object if the summary_column value is 0). You can reach the conditional formatting UI through the property inspector of the Dept and Class headers.
Note that this will only hide the dept repeating frame, so your headings should be in this repeating frame. This may be fine in your case, as you have only one record per page.
The max no of records that you have set should have no effect on the above suggestion.
