N-Level Parent-Child Aggregation

Question

Hi,
We have an account table and a transaction table, the account schema is
Account ID
Account Name
Parent Account ID
The account hierarchy level is N-Level. The business user can add account/sub account.
Account ID | Account Name | Parent ID
1 | FX Gain (Loss) | null
2 | Asia FX Gain (Loss) | 1
3 | China FX Gain/Loss | 2
4 |Japan FX Gain/Loss | 2
5 | Promote Fee | null
In this table, the hierarchy is
FX Gain (Loss)
|- Asia FX Gain (Loss)
|- China FX Gain/Loss
- Japan FX Gain/Loss
Promote Fee
Promote Fee & FX Gain (Loss) are the root. And Promote Fee doesn't have any child or grant-child.
======================
Transaction Table schema is
Transaction ID
Account ID
Amount
Date
Sample data
Transaction ID
Account ID
Amount
Date
1 | 3 | 10.0 | 12/1/2009
2 | 3 | 20.0 | 12/2/2009
3 | 4 | 30.0 | 12/1/2009
4 | 5 | 40.0 | 12/1/2009
We want to use BusinessObjects to build account drill-down reports with aggregated transaction amount.
For example, the report likes this
Account Name | Amount
FX Gain (Loss) | 60
Promote Fee | 40
User can drilldown FX Gain (Loss):
Account Name | Amount
Asia FX Gain (Loss) | 60
Then, drilldown Asia FX Gain (Loss):
Account Name | Amount
China FX Gain/Loss | 30
Japan FX Gain/Loss | 30
How to design the universe and the report? Any sample?
Your help would be highly appreciated.

Hi,
double click the Application Module to open the AM editor. Select the data Model category. On the right hand side you see what is selected for use in an application, on the left hand side is what you have available as View Object. To create T1-->T2-->T3, you
- Select T1 and move it to the right
- Select T2 under T1 on the left and move it to the right under T1
- Select T3 under T2 on the left and move it under T2 in T1 on the right
