RFC destination for client copy in systems with component FINBASIS

What causes this issue?

The system could not find any suitable RFC destination for processing
for client <(>&<)>1.
This note also appears if an RFC destination was found but this does not
work.
RFC destination: <(>&<)>2
Error text: <(>&<)>3

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Start transaction FINB_TR_WZ to create a new RFC connection
or perform the following steps manually:
Create an RFC destination with the target source client of client copy
(in this case, <(>&<)>1).
Check whether the RFC destination works in transaction SM59. To avoid
errors when assigning the password or the authorizations of the RFC
user, use the authorization test Test -> Authorization.
Enter the RFC destination:
Transaction: FINB_TR_DEST (Destinations for Transport Methods of the
Financials Basis)
Client: <(>&<)>1
Start the client copy again.
