A guess based on your indentation ... are there a lot of commands in your code which you didn't show here? That's OK if you don't want to, but I have a point.

Are you sure a command between SCAN and REPLACE isn't changing you to another work area? REPLACE without IN clause works on the currently SELECTed work area.

Another question, if you *did* show all your code in your question: are you aware that REPLACE takes a scope clause?

You can:

REPLACE field WITH value ALL
(same as:
SCAN
  REPLACE field WITH value
ENDSCAN)

or:

REPLACE field WITH value FOR condition
(same as:
SCAN FOR condition
  REPLACE field WITH value
ENDSCAN

HTH,
