OPM Intercompany, 1 Ledger w 2 OUs w duplicate intercompany invoices for the same transaction

I am more familiar with Oracle Financials and new to OPM.  I am accustom to running the Create Intercompany AP/ AR Invoice programs in the Financials, but OPM is also creating intercompany invoicing.

My new client had a new install beginning this year and they are creating manual je's to eliminate the duplication.  For example, an Inventory receiver  transaction will DR Inventory and CR Intercompany Expense and PPV, but

for the same transaction, and entry is created involving the above and COGS.  Is there a recommended setup to avoid this duplication?
