Narrative:

The whole event started out by the fact that I programmed the FMC wrong while in cockpit preparation phase of the flight. Instead of putting ABCCBD01 in the route page; I put ABCCDB01. This programmed the FMC to sna instead of san. Both routes have the same departure procedure of the BOACH2. Both pilots briefed what they were supposed to brief and went through the correct procedures on the ground. However; it was missed and it shouldn't have. The routes were very similar and we did not go through the entire route. We only looked at the first few fixes instead of the whole route. This made us turn in flight to hec instead of tnp. I made a typing error on the FMC and some how; both of us missed the mistake by not looking at the entire route. They looked so alike that I did not catch it. I believe I made this mistake because I was fatigued. I had not received much sleep the night before because of being rerouted. I was waiting for 5 hours in another airport before even starting my day. This was the only way for scheduling to catch me up with my original pairing. I knew I was tired; but at the time I did not think I was unable to perform my duties. I felt I made this simple mistake because of that. I should have called in fatigued but the pressure of the operation and time frame of the last round trip being so short prevented me from doing so. I felt tired but did not think that fatigue was hindering my job. In this case it was a big factor in making the mistake in programming the FMC.
