Problem

-- Possible duplicate transfer are routed by decision rule

-- Transfer can be integrated twice by the backend

Resolution

To prevent SwiftNet duplicate transfer to be routed by decision rule:

** In Gateway configuration > SwiftNet: Accept possible duplicate transfer must be set

** In decision rule, add the parameter "possible duplicate = No", so your decision rule should look like:

- direction = I

- protocol = SWIFTNET

- possible duplicate = N
