Human Factors; Procedure
Captain and I planned and briefed the DYAMD2 arrival into SFO with the FMS Bridge visual approach 28R with the ARCHI transition. We briefed the altitude difference at ARCHI; 7000 on the STAR and 8000 on the approach. ATC cleared us to descend via the DYAMD2 except maintain 8000 after ARCHI. Talked to final approach controller; told us to expect the ILS 28R. I put it in the box with the ARCHI transition; it defaulted to 7000 feet at ARCHI and we didn't catch that. Just before reaching 8000 we were now cleared for the approach. Captain called for a lower altitude; while in LNAV and VNAV. We ended up crossing ARCHI at 7000 and were expected to cross it at 8000.
ATC cleared us to descend via the DYAMD2 except maintain 8000 after ARCHI. Talked to final approach controller; told us to expect ILS 28R. First Officer entered it in the box with the ARCHI transition; it defaulted to 7000 feet at ARCHI and I did not catch the error. We were now cleared for the approach. I called for a lower altitude; while in LNAV and VNAV. We crossed ARCHI at 7000 and were expected to cross at 8000.
B737 flight crew reported missing a crossing restriction at ARCHI on the DYAMD2 arrival into SFO; citing differing charted altitudes for crossing ARCHI as contributing.
