## Discrepancy

AFTER LANDING, CLEARING RUNWAY, BOTH MCDU SWITCHED TO MENU PAGE AND NO FMC PROMPT WAS DISPLAYED.  CAPTAIN ND HAD VTK FLAG DISPLAYED.  DID NOT NOTICE THE F/O ND.  AFTER ABOUT 1 MIN EVERYTHING RETURNED TO NORMAL, BUT FMC DATA FOR FLIGHT WAS LOST.  ACFT GROUNDED.  ACCOMPLISHED FIM 34-61, TASK 836, FMC DOES NOT OPERATE, BOTH FMC'S RESET ACCOMPLISHED, AND ALL GROUND FUNCTIONAL TESTS PASS.
