What about my suggestion of using linked tables (rather than importing)?
Is there a business need to physically remove rows from one place and put
them somewhere else?
Would it suffice to have a row "marked" as "Closed", but left in the same
table?
If you need a copy of the data, identifying which rows are "Closed", you
could use a simple backup copy of the entire database. This has the added
benefit of including all the other contexts at the time of "closing the
books."
