Inter Unit Transfer Journal Entry unbalanced

We have two AM Business Units - one AM BU records to the Actuals Ledger and the second records to the Reporting Ledger.  Both ledgers are in the same GL BU.

When an asset is transferred from one AM BU to the other AM BU, the accounting entries are out of balance because the transactions are split between Ledgers on the same BU.

To avoid this, we retire an asset in the existing BU and add it to the new BU losing history.

Anyone experience this issue?  If so, would you be willing to share your work-around?

thank you,

Andrea
