Narrative:
While on approach into rksi; we were assigned the GUKDO1N arrival. At approximately 20 miles southeast of the field; we given radar vectors and told to descend to 5;000 feet. The controller said cancel all restrictions. The PF (pilot flying) asked the pm (pilot monitoring) to extend the centerline from if (initial approach fix) fasap; per normal practice while being radar vectored. At approximately 8 miles west of the field; the controller cleared us direct to danan and cleared us for the approach. We were very close to danan at that point. We immediately programmed danan into the FMC (flight management computer). The pm monitoring then reprogrammed the full approach back into the FMC.while that was going on; having been cleared for the approach we started our descent to 3;000 feet. We crossed danan about 4;800 - 4;500 feet. About 1 minute later; ATC informed us we missed a crossing altitude at danan. Danan was both listed on the STAR (standard terminal arrival route) and approach plate. When [we were] told in a terminal environment [to] cancel all restrictions and are given radar vectors; we were expecting to descend and turn when instructed by ATC. However; being put back on a full approach with very little time to prepare for it led to missing the altitude restriction. The controller told us 'don't worry about the altitude.' we continued the approach with no further incident. Lesson learned is be prepared for last minute changes.
