Two Tier ERP Integration:

Integration is crucial for Two-Tier ERP scenarios, as understanding end-to-end business processes, including both master and transactional data flows, is vital for customer success. It’s important to identify integration requirements early in the process. SAP S/4HANA Cloud will also need to integrate with various other solutions within the customer’s system landscape. Two-Tier ERP offers multiple deployment options, For instance, let's look into one of the deployement option where companies running their main ERP systems (headquarters) on SAP S/4HANA Private Cloud Edition or SAP S/4HANA on-premise can connect to subsidiaries using SAP S/4HANA Public Cloud Edition.
