Narrative:

On departure, FMC commanded 360 degree heading prior to intercepting 342 degree right of sfo. We were on a silent 7 departure from oak. Controller immediately issued headings. We logged software discrepancy with air carrier maintenance. After discussion with the controller (no paperwork was filed) we decided the time element during an SID or STAR really does not safely allow a switch to raw data west/O a real possibility of violating another aircraft's airspace.
