Narrative:

Incorrect FMC programming. Programmed FMC in oak (aok.las.01) and selected runway 25L to get the entire route for the tragar arrival. I closed the route discontinuity between the arrival and runway, but did not look close enough to see that the fixes from tragr, then kimme were not listed. While we were on the arrival, we did not have the legs page up. We noticed the aircraft turn about 20 degrees left (which we knew was incorrect). It took us a few seconds to figure out what was going on. ATC noticed our turn and asked if we were headed to shand, we said yes, and ATC gave us a right turn to 130 degrees and gave us a phone number to call. On the ground we called company ATC specialist, who called back and said all was ok. I believe this problem was caused by a number of factors: 1) database in FMC was incorrect, problem was noted in flight release. 2) to quick to program FMC. 3) legs page was not displayed during arrival.

Title: A TRACK DEV ON THE TRAGR RNAV 2 ARR TO LAS, NV.

Narrative: INCORRECT FMC PROGRAMMING. PROGRAMMED FMC IN OAK (AOK.LAS.01) AND SELECTED RWY 25L TO GET THE ENTIRE RTE FOR THE TRAGAR ARR. I CLOSED THE RTE DISCONTINUITY BTWN THE ARR AND RWY, BUT DID NOT LOOK CLOSE ENOUGH TO SEE THAT THE FIXES FROM TRAGR, THEN KIMME WERE NOT LISTED. WHILE WE WERE ON THE ARR, WE DID NOT HAVE THE LEGS PAGE UP. WE NOTICED THE ACFT TURN ABOUT 20 DEGS L (WHICH WE KNEW WAS INCORRECT). IT TOOK US A FEW SECONDS TO FIGURE OUT WHAT WAS GOING ON. ATC NOTICED OUR TURN AND ASKED IF WE WERE HEADED TO SHAND, WE SAID YES, AND ATC GAVE US A R TURN TO 130 DEGS AND GAVE US A PHONE NUMBER TO CALL. ON THE GND WE CALLED COMPANY ATC SPECIALIST, WHO CALLED BACK AND SAID ALL WAS OK. I BELIEVE THIS PROB WAS CAUSED BY A NUMBER OF FACTORS: 1) DATABASE IN FMC WAS INCORRECT, PROB WAS NOTED IN FLT RELEASE. 2) TO QUICK TO PROGRAM FMC. 3) LEGS PAGE WAS NOT DISPLAYED DURING ARR.
