## Discrepancy

ENROUTE RECEIVED A SINGLE FMC OPERATION MESSAGE ON THE CDU SCRATCH PAD WITH VTK DISPLAYED ON THE F/O'S ND MAP DISPLAY.  FOLLOWED THE QRH AND PLACED THE FMC SWITCH IN "BOTH ON L". CHECKED THE FMC INFO ON POS SHIFT PAGE 3/3 AND FOUND THE FMC -R IS BLANK. ACFT GROUNDED. T/S IAW FIM 34-61. COULD NOT DUPLICATE FAULT.  FMC OPERATION RESTORED. NO 30 DAY HISTORY.  OK FOR SERVICE.
