I suspect these things might happen because either:
1) The codeshare number is some discount seat that the partner airline bought.
2) The two carriers compete in the same market. I know that the OneWorld alliance has some funny rule stating that you cannot earn AA miles if you fly on BA flights from the US to UK if AA flies the same route.

Well, no actually it was a full C-class fare that I was flying on, so hardly discounted. So that doesn't explain it really.
The AA/BA issue was an anti-trust measure by either the British and/or US governments because both carriers together occupy such a large share of the transatlantic market.
I would really like to see someone from one of the airlines or the alliance explaining why one does not get any miles under these circumstances.
