To integrate SAP S/4HANA Cloud Public Edition with another SAP public cloud solution, you should

use SAP Integration Suite and predelivered APIs. SAP Integration Suite is a cloud-based integration

platform that provides a comprehensive set of capabilities to connect applications, data, and

processes across different environments. Predelivered APIs are predefined interfaces that enable

communication and data exchange between SAP S/4HANA Cloud Public Edition and other SAP public

cloud solutions, such as SAP SuccessFactors, SAP Ariba, SAP Fieldglass, and SAP Concur. SAP Process

Orchestration and SAP Cloud Connector are not the correct technologies for this scenario, as they are

mainly used for integrating SAP S/4HANA Cloud Public Edition with on-premise or hybrid

systems. Reference = SAP S/4HANA Cloud Public Edition - Integration, SAP Integration Suite, SAP
