Narrative:
On the seavu approach to lax; we were cleared to descend via the seavu for runway 25L. Up at altitude we programmed runway 24R in anticipation of our arrival runway and the VMC at lax. Late programming on the FMC to change runway 24R to runway 25L caused us to have a slight overshoot of the inbound course (249 degree radial) at approximately 40 mi out of lax. We corrected immediately. ATC inquired about our heading and we informed the controller we were correcting. Immediate programming of the FMC upon descent clearance and/or verifying the correct runway is programmed.

Narrative: ON THE SEAVU APCH TO LAX; WE WERE CLRED TO DSND VIA THE SEAVU FOR RWY 25L. UP AT ALT WE PROGRAMMED RWY 24R IN ANTICIPATION OF OUR ARR RWY AND THE VMC AT LAX. LATE PROGRAMMING ON THE FMC TO CHANGE RWY 24R TO RWY 25L CAUSED US TO HAVE A SLIGHT OVERSHOOT OF THE INBOUND COURSE (249 DEG RADIAL) AT APPROX 40 MI OUT OF LAX. WE CORRECTED IMMEDIATELY. ATC INQUIRED ABOUT OUR HDG AND WE INFORMED THE CTLR WE WERE CORRECTING. IMMEDIATE PROGRAMMING OF THE FMC UPON DSCNT CLRNC AND/OR VERIFYING THE CORRECT RWY IS PROGRAMMED.
