(2) Screen Requirement It must be difficult to prepare all input items in ISO 20022 messages for the CBMNET terminal screen because each ISO 20022 message contains more than one hundred tags and items. Therefore, in the external design phase, CBM should discuss with participant FIs which input items to implement on the CBM-NET terminal screen. (3) Form Requirement ISO 20022 adoption does not have particular documents or forms. (4) Data and Information Requirement As described above, ISO 20022 messages have versions and each version may be updated annually. Once the version is set, it will be unchanged at the time of go-live at least. The version should be defined at the beginning of the external design phase. For any changes (such as version upgrades) in the messages after go-live, CBM must follow up the latest status and upgrade the system if necessary. (5) External Interface Requirement The external interface specification will be designed by the CBM-NET Phase 2 application vendor based on the ISO 20022 standard of each message type and will be confirmed by CBM in the external design phase. (6) Prerequisite For the specification, CBM will conduct required review and confirmation in timely manner. Since detail of adopted ISO20022 messages will be included to the STP specification, it will be disclosed and provided to the FIs with coordination of CBM 32
