Narrative:
We were departing ont on PRADO5.pdz departure and unbeknownst to us the FMC had dropped the routing and gave us direct to thermal instead of the 130 degree heading to nikkl then trm. As a result, we picked up a heading of 100 degrees. As we rolled out, socal directed us to turn to a 120 degree heading and continue. Nothing else was said. We immediately understood the mistake and asked if he wanted us to correct to 130 degrees to socal controller said 120 degrees would be fine. Supplemental information from acn 430407: prior to departure, FMC was loaded with prado 5 departure. First officer was at controls, I was monitoring. An monitoring pilot, I should be on raw data versus map status.
