We can derive EQM from the base if we know the fare class and the flight number. It doesn't matter who operated the flight, the carrier that preceeds the flight number is what matters. A BA codeshare operated by AA will earn according to the BA charts; similarly, an AA codeshare operated by BA would earn according to the AA charts. AA can even sell you a BA codeshare operated by AY.
If we knew the route, flight numbers as flown and fare classes, we could assist in determinimg if your earnings are correct.

Thanks, James. I'm putting the relevant info down below, including fare classes, earning %s, and my calculations. Given the earning %s, my calculated RDM and deposited RDM are the same, 4448 RDM. Per the charts, EQM earnings should be the same, but it's increased in my account by only an even 2500. (And I'm sure the increase is only 2500. I track all EQM in a spreadsheet.)
If I'm overlooking some fine print or calculating something incorrectly, I'd be satisfied to know about it. If not, I suppose I'll have to figure out which airline(s) I need to contact.
Note: I've read in the BA & AA forums about this happening sometimes, but on the same booking, I was given a different confirmation code for one segment (FCO/LHR), and no reported AA codeshare flight number for it. And as you can see from the screenshot, that RDM was reported from BA. All the others from AA. All the flights were on BA metal.
My calculations
Reported mileage activity
ETA: I just noticed that in mileage activity, the BA flight no. is 551. In my trip confirmation email, it's 553. I don't think that affects anything for this issue, as the route's the same.
