Copying Parent account value to another account

Hello Experts

I have a requirement in SAP BPC 7.5 NW where:

1. Source account - A310 is a Parent account with 4 level of hierarchy.

2. Destination account - A10601 is a base member

We want to copy the value of A310 to A10601.

[note: A310 is caluclated on the fly as it is a parent node.]

In BPC MS version we had "calc_dummy_org" to do the same.

Please suggest how to calculate the same.

Thanks

Abhishek
