Analytical function SUM() OVER (PARTITION BY ) in Crosstab

Question

I am trying to resolve this from a very long time. I have an amount column that has to be grouped on Year, but all the other columns grouped by month. I am trying to achieve this using analytic function SUM(Case when (Condition1 and Condition2) then Sum(Amount) else 0 end) OVER ( PARTITION BY Account, Year), Where Account, Sub Account are the left axis columns. Now, column displays the values correctly, but at different rows. This is confusing.............
For Ex: For Account 00001, there are 3 sub accounts 1000,2000,3000. For Sub account 3000, conditions 1 and 2 are satisfied, so it should display the Amount in the row corresponding to Sub account 3000, and 0 for remaining Sub Accounts. And the Total amount of all the sub accounts, which will be the same as amount for SubAccount 3000 should be displayed in the row corresponding to Account 00001.
But I get blank rows for 1000 and 3000 Sub accounts and Amount displayed in 2000 Sub account, and blank for Account 00001 also.
When I created the same workbook in Tabular form, the same amount is displayed for all the SubAccounts of a single Account.
When I used this CASE statement in TOAD, I figured that this is due to the Analytic function. When I use a group by clause as shown below instead of partition by, I get the results I need.
SELECT (Case when (Condition1 and Condition2) then Sum(Amount) else 0 end), Account, Sub Account FROM tables WHERE conditions GROUP BY Year, Account, Sub Account
But I cannot use groupby for whole SQL of the workbook as I need the other columns with page item 'MONTH' not 'Year'.
Could somebody please help me with this?

Answer 1

Hi,
In your tabular form do you get the correct total display against all you subaccounts and account? If this correct then you can use case to ensure that the total is displayed only for the single account.
Once you have the correct totals working in a tabular form it is easier to re-produce what you want in a cross-tab.
