Hi Anthony
It seems as though SAP S/4HANA Cloud Public Edition does have a REST interface (https://api.sap.com/products/SAPS4HANACloud/apis/REST) and as such, we could use Connector Xpress 2.0 (REST CX) to create a dynamic connector and manage the endpoint.
For more information about Connector Xpress 2.0 features and usage - please refer to the official documentation https://techdocs.broadcom.com/us/en/symantec-security-software/identity-security/identity-management-and-governance-connectors/1-0/connectors/Connector-Xpress-2-0-for-REST-Applications(14-4-1).html
Hopefully we can also hear from other customers which may have implemented a similar solution.
Regards
Rinat
