Reference account &1 is acct determination relevant; used more than once

What causes this issue?

You have assigned several G/L accounts to reference account &V1&, such
as G/L account &V2&. This reference account is account determination
relevant.

System Response

When copying the account determination from one chart of accounts of
the reference company code to the chart of accounts of the target
company code, the copied account determination can only be entered in
one of the G/L accounts.

How to fix this error?

Delete the multiple entries or change the reference account to an
account that is not account determination relevant.
Another possibility that would suffice is to select one account before
executing the function <ls>Create account determination</>.
