Just based on your posted query, it looks like what you should have is...

Update Emp_Loan  Set LDeducted=DSum("[DAmount]", "[Emp_Loan_Deducted]", "EmpID=" & Emp_Loan.EMPID)

This assumes EMPID is a number field.

The query has no specific reference to any form or report but you can run it anywhere you like.  

You cannot create an update query in Access that has a Group By expression  or any aggregate function Sum/Count/Avg etc; so the previous responses will not work.
