This KBA note will be the central document to consolidate all information and commonly asked questions regarding the upcoming SAP Infrastructure upgrade from June 2022.
Between the months of June 2022 and August 2022 SAP will upgrade the back-end infrastructure where your SAP Multi-Bank Connectivity (MBC) tenants are located. The result of the upgrade will be that in the long-term, the IP Addresses SAP Multi-Bank Connectivity (MBC) uses to make outbound connection requests to other systems will change. In the short-term both the ‘old’ IP Range and the ‘new’ IP Range will be valid.
The transition from the old range of IP Addresses to the new range of IP Addresses will occur seamlessly. Importantly, the old range should be retained until the transition is completed. Communication of the status change will occur separately later.
The change to outbound IP address range may impact transactions in these scenarios:
- Bank responses delivered by MBC to connected SAP On-Premise systems (e.g. S/4HANA On-Premise or ECC On-Premise) or Non-SAP ERP systems who have implemented allowlisting (formerly: whitelisting);
- Payment instructions delivered by MBC to connected external Host-to-Host (H2H) financial institutions or 3rd-Party Service Providers who have implemented allowlisting (formerly: whitelisting).
The MBC Team’s goal in managing the transition is to prevent the possibility that any systems receiving requests from MBC reject them due to IP Address allowlisting.
