Reassignment of hierarchy nodes dynamically

Question

Hi Experts,
I have a requirement wherein I need to re-assign the hierarchy node for an account based on Functional area.
Currently, we load 0ACCOUNT info object with hierarchy defined in KDH3 transaction in R/3. Here, the account 650000000 is defined under local accounts node of the hierarchy. Hence, when we use the 0account infobject in BEx with hierarchy activated, all the records in transaction data with account no. 650000000 are aggregated under local accounts node.
However, the user wants us to check the functional area for each of the record with 65000000 account and re-assign it to a different node of the hierarchy. For example, if the transaction data has account number 65000000 and functional area 400, then the record needs to be aggregated under a different node in hierarchy, say overhead costs. Similarly, if there is another record with account 650000000 and functional area 300, then the record needs to be aggregated under Sales & marketing.
How do we handle such conditional assignment of hierarchy nodes?

Answer 1

Hi,
I really doubt if dynamic reassignment of hierarchy nodes is possible in BW, but could be wrong.
Alternatives which you can consider
a. A flat hierarchy modeled in the dimension of the cube i.e. higher levels of 0ACCOUNT can be filled during transformations based on functional area. Major disadvantage here is that any change to the hierarchy or assignment could require reloads depending on your requirement i.e. touch history data or not
b.Customized Hierarchy created by combining the original hierarchy and the assignment details
for eg 
Leaf Node: 650000000_400 under parent Overhead Costs
Leaf Node: 650000000_300,under parent Sales & Marketing
