I won't ask why you want to store the data redundantly...
In the query builder, add the two tables Main and ModMain. If there isn't
already a relationship between the two tables, drag the RefNo field from one
of the tables and drop it on the RefNo field of the other table.
Add the three other fields from table Main to the grid and convert the query
to an Update query (there's a button on the button bar, or you can go to the
Query menu while the query's open in Design view).
Underneath the Document_Type field in the grid, put
[ModMain].[Document_Type_UPDATED] in the "Update To:" row. Do the same for
the other two field (putting, of course, the appropriate field underneath)
