Earlier tonight, I bought tickets on a UA/ANA codeshare (UA7941, operated by ANA for IAD-NRT) and called UA CS and got the ANA reservation #. When I tried to assign my seats on ANA's website, it said:
*We cannot display the selected reservation. Please contact your travel agency, or contact ANA International Flight Reservation and Information Center.(Error Code: W_H26)"
Is there a time window that I need to wait before it shows up on ANA's system, such as 24-48 hours? ANA's reservation line is currently closed. I still have plenty of time (flight isn't until mid March of 2015

) so it's not urgent but am curious if the ticketed reservation isn't immediate between the two carriers.
