Narrative:

[We] loaded [runway] 24L instead of 25L with the riivr transition. ATC gives this clearance late with changes requiring excessive pilot workload. FMC kept saying we were 2;000 ft high; although after manually looking at the data we determined we were on profile. This happened for the entirety of the approach. This was very distracting and caused us to miss the fact that the wrong runway was loaded. Late clearance and erroneous data caused us to get behind. ATC caught our tracking error and gave us a vector to intercept 25L localizer. The rest of the approach was uneventful.

Title: SCT gave a late RIIVR TWO Runway 25L clearance to a B737 crew who then loaded the FMC correctly; but left the arrival Runway as 24L; which made them high on profile and caused a track deviation.
