This  type  process is called  Encapsulation  and should be  done in

windowing - but more limited.  Depending on the  technique ( program or
file ) encapsulation you  must  ensure  all  entries and  exits  from (
lets talk in terms of  files) handle the roll back  and forward of the
dates on  Input/Out put.

You should also  strongly  consider your Ad-Hoc Users and EIS  systems  as
they  will  perhaps make decisions  based on the file data and distort or
give an incorrect  view to the  user.

JUST a  high  level summary.

Please make sure this is well documented and a  part of your post 2000
activities to correct.
