Let's say, you purchased IB1234.
IB1234 is codeshare of AA2345/FI3456
You can credit IB1234 to IB FFP, or AA FFP, or BA FFP, or any Oneworld FFP.
(As other posters write, earning ratios are different)
You can't credit AA2345 to any FFP instead of IB1234. (You didn't purchase AA2345, so you can't credit it)
You can't credit FI3456 to any FFP instead of IB1234. (You didn't purchase FI3456, so you can't credit it)
