Hierarchy to use in Script Logic

Hello Experts

I am trying to transfer the Profit/(Loss) from P&L to Reserve Account in the Balance Sheet by running a script logic.

I am using BPC 10 NW 7.4

The hierarchy of  P&L, is designed to calculate the Profit of Loss for the period. I wrote the script by selecting node in the hierarchy and transfer to reserve account. However it is not working.

To test my logic, instead of hierarchy, I tried with a base level account member, it is working.

Following is the body of my logic.

WHEN ACCOUNT.PARENTH1

IS <P&L AFTER TAX> // The node which aggregate the value

REC (EXPRESSION = %VALUE%, ACCOUNT = <RESERVE ACCOUNT>)

How could I resolve it?

Your expert ideas are much appreciated

Kind Regards

Abraham
