So you are saying that you are using dreport or
rreport to import the file and you are worried that
someone will try to go into Inquire/Update/Add on this
file at the same time?  If that is the case you can
simply use the -u flag on the dreport/rreport process
to avoid this error.

Alternately, you could use dclerk/rclerk with @menu
processing to import the file, and thereby avoid
request output altogether.
