Connecting your ERP system to multiple banks can be complex—but with SAP Multi-Bank Connectivity (MBC), organizations gain a centralized, secure, and efficient way to manage bank communications.

In this blog, we walk you through:

• The architecture and landscape
• The onboarding process
• The roles and responsibilities involved in a successful integration

Why SAP Multi-Bank Connectivity?

The SAP Multi-Bank Connectivity connector acts as the central communication hub between your ERP system and banks or financial institutions.

Every message exchanged—payments, statements, etc.—flows through this connector, ensuring:

• Full transparency of bank communication
• Real-time updates of payment status and cash positions
• End-to-end traceability using the Manage Bank Messages SAP Fiori app (SAP S/4HANA Cloud Public Edition)

Every message sent through this connector includes key details like sender and receiver IDs, message type, file name, and message content. Additionally, it contains important context information such as Swift parameters or approval user details, which are essential for seamless bank interactions.

System Landscape Overview

Using SAP Multi-Bank Connectivity truly enhances your control, efficiency, and transparency in financial accounting. This solution automatically updates payment statuses and cash positions in the ERP system as soon as new information is available from the banks.

SAP Multi-Bank Connectivity has two main environments: test and production.

It's important to connect these to the matching systems—test-to-test and production-to-production—on the customer side. These test and production systems are kept separate for safety and further protected by different security measures.

In the SAP BTP environment, SAP Multi-Bank Connectivity is a managed service. This means the subaccounts won't be visible under the customer's global accounts in BTP. Still, customers can easily access the SAP Multi-Bank Connectivity applications to set up and monitor their ERP connections.

There are two connections that need to be setup when you get onboarded to SAP Multi-Bank Connectivity: the first from your ERP system to SAP Multi-Bank Connectivity, and the second from SAP Multi-Bank Connectivity to your banks or FSIs.

Onboarding Process – End-to-End Journey

The onboarding process is structured into several key steps to ensure a smooth and secure integration:

1. Configure Test ERP and Connect to MBC Test Tenant

Set up your ERP test system and establish the connection with the SAP Multi-Bank Connectivity (MBC) test tenant. Ensure that you have the required authorizations to access MBC applications.

2. Configure MBC Test Tenant and Connect to Bank

Complete the configuration of your MBC test tenant. The SAP MBC team will then establish the connection between your tenant and the respective banks or financial service institutions (FSIs).

3. Perform End-to-End Testing

Execute comprehensive end-to-end testing to validate the entire integration flow before proceeding to the production environment.

4. Configure Production ERP and Connect to MBC Production Tenant

Set up your production ERP system and integrate it with the MBC production tenant. Verify that access to all required MBC applications is properly assigned.

5. Configure MBC Production Tenant and Connect to Bank

Finalize the configuration of the production MBC tenant. The SAP MBC team will connect it to your banks or FSIs.

6. Execute Penny Testing

Perform penny testing in the production environment to confirm that transactions are successfully processed between the ERP system and the banks.

7. Production Support and Maintenance

After going live, follow standard SAP support procedures for any issues or inquiries.
