I think the question is still ambiguously stated. Here is an example that (I hope) illustrates the question the OP is trying to ask:

QF operates a flight between LAX and SYD. AA codeshares on the flight. The question is whether AA will show its own award inventory on that flight.

If this is the question, I thought that: (1) AA offers its own award inventory only on flights operated by AA; and (2) if you want to use AA miles for an award on a flight operated by a partner airline (not AA), then the award has to be available on the inventory of the operating airline (QF in this example) and you would have to use the "AAdvantage Participant Airline Award Chart" to determine how many miles the award costs.
