SLA:INVOICE LIABILITY AT PAYMENT.

I've been playing around with SLA rules to identify the "Liability" company code at the time of Payment on the invoice. Im using the "Payment" event class. It seems like the sources below all return Invoice liability based on the default and not the liability of the invoice payment.

1. Invoice Liability Account of the Invoice Payment
2. Invoice Liability Account of the Invoice Payment
3. Invoice Liability Account

So here is my scenario. Please test at your end and if possible explain why oracle behaves as described:

1. Setup the Default AP Liability at the operating unit to say 101.2XXXX
2. Make sure that the Supplier has no AP Liability.
