We are migrating from SAP ECC to SAP S/4 HANA Cloud but we are not migrating from SAP PO to CPI.
I am having few doubts regarding SAP S/4 HANA Cloud Integration with SAP PO 7.5. .
1. How to integrate existing IDoc, RFC, PROXY interfaces with SAP PO after S/4 HANA migration?
2. Which adapters will be available in S/4 HANA Cloud to integrate with SAP PO?
3. Are there any interfaces/adapters which will not work once migrated to S/4 HANA?
4. Is it mandatory to have SAP Cloud Connector installed on PO in order to integrate with S/4 HANA Cloud or we can integrate directly with published APIs using standard SOAP/OData/HTTP adapters in PO?
I would appreciate if anyone could please help me with this or provide any blogs to refer.
