This involved party is the one the liability is assigned to. It is defined as a mandatory client party, which may not be a temporary address.

The drawer is the party who issued the check. This party should be recorded if the collecting bank simultaneously is the bank that uses the application so that settlement of the remittance can be made directly with the issuer (customer of the collecting bank).
