Code sharing is something entirely different. Two member of an alliance don't have to code-share.
I suspect, what the OP was asking was that Saudia is not showing up on the list of airline partners.
By definition all members of an alliance are partners. This raises the question, can you earn Medallion Qualifying miles on Saudia? If yes, it must be a DL partner. Then why isn't it showing up on the list or airline partners.
It is possible to be members of the same alliance while both: not code-sharing on some/many/any/all flights; and not giving flight credit for some/many flights. What would be unprecedented since the three big global airline alliances came into being would be denial of any credit for all flights of an alliance member. It is still to be seen how this is going to go over.
