## Discrepancy

DIVERTED DUE TO FLIGHT CREW REPORTING THAT THEY CANNOT GET THE USEABLE FUEL TO TRANSFER OUT OF THE OUTER FUEL TANKS. WING OUTER VALVE INDICATIONS SHOWED AMBER AND CLOSED. FALSE INDICATIONS ATTRIBUTED TO SDAC 1 DUE TO OTHER ERRONEOUS FAULTS. FUEL TRANSFER IS NOT POSSIBLE AT CRUISE. CREW/DISPATCH DECIDED TO DIVERT WITHOUT MCC CONCURRENCE.  RESET SDAC 1 AND 2.
