Might I inquire why?
One does not normally duplicate data in a well normalized database.

Just need to know whether its possible

it's possible.
"cheat" on the sql
Do this first using the query editor.
I'll make a copy of both tables, use the QE to create a select query that returns the correct records, then convert to an update and run on the copies. If all goes well, I then switch to the SQL view and copy the sql for use in the VBA code altering to suit variables as needed.
HOWEVER< I rarely do this to copy one value from one table to another, especially if there is a related field.
