## Discrepancy

CATERING REPORTED SMOKE TO F/A WENT BACK AND SMELLED SMOKE ABOUT 4 ROWS PRIOR TO THE AFT BULKHEAD.  OTHER CREW MEMBERS ALSO NOTICED THE ODOR.  FIRST F/A ALSO REPORTED SEEING SMOKE IN THE AFT PART OF THE AIRCRAFT.  ISOLATED MAIN ODOR TO APU BATTERY OVERHEATING.  REPLACED APU BATTERY AND APU BATTERY CHARGER PER MM.
