Detailed and Summary reports in the same rdf

Question

Hi,
I am using reports 9i
The problem
I wish to create three reports (one in each section) from the same sql statement
1) A detailed report
2) A summary by Country.
3) A summary by Currency
The SQL pulls in the data at the detailed level , report (1), no problems here
The SQL return two attributes Country and Currency which I want to group the totals to make reports (2) and (3). I use repeating frames to handle the different Countries and Currencies.
Question
How should I structure the Data Model to easily build the reports above. I have successfully created the Country summary, report (2) by creating a Group which includes summary columns breaking on the Country attribute. All going well so far.
I attempted to create an additional group with summary columns breaking on currency however, when I ran my report this report was breaking on Country and Currency.
The data model currently looks like
Query ---> G_CURRENCY --> G_COUNTRY --> G_DETAIL
Perhaps the issue is not with the data model, but something I am doing in the in the Paper Layout?
Any help gratefully appreciated.

Answer 1

I don't think you can do that with only one SQL in the data model though.
If I were to do that report, I will have to options .
OPTION 1
1.) Create 2 SQL in the data model. One SQL will be for the Detail report and either one of the summary (e.g. Currency and Detail ). The other SQL will be for the remaining summary report ( e.g. Country) .
Then in your paper layout, you just add 3 different groups/repeating frame - one for each group in the data model. Each frame is independent of each other
2.) The other option is to use aggregates in your SQL. You may use CUBE which is an extension of the GROUP BY clause. Your SQL would look something like
SELECT COUNTRY, CURRENCY, SUM (col1), COUNT(col2)
FROM table1, table2
WHERE <conditions>
GROUP BY CUBE (COUNTRY, CURRENCY).
The records returned by this SQL will include the total for the country and currency, as well as the grand total for all the records. You should try this to see what records it will return or look into the Oracle 9i DataWarehousing guide document for more details.
In your paper layout, you will again have three groups/repeating frame independent of each other. But you have to control which records are to be printed by checking the values of the group columns.
I hope this helps.
