How to not Intercompany Invoicing

Hi

We've set up inter company transactions for invoicing across operating units. Now business does not want invoicing for such cases. We've end dated inter-company relation flow but nature of transaction is not changing for sale to stock transfer. (Shipment is still creating accrual liability).

Are we missing any set up apart from this. We checked couple of profiles but they are useful only at high level (il.e. they may not work for partial changes)

Note that nature of transaction should change only for cases between OU A and OU B. It should continue sales-cogs for OU A and OU C
