Re: duplicate record error when updating a physical file

I don't see the definition of the keylist CDEB_KEY02  or the subroutine
MOVE_DATA in the sample code that you submitted, but the error can occur if
you CHANGE the value of one of the key fields of the file that you are
attempting to update.  In this situation, the Update operation will fail if
there is already a record in CDEBP that has this key value, since it has
UNIQUE specified.
