The customer that I work with are planning to implement S/4 HANA Cloud for their ERP needs. Though there is less scope to customize and do configurations in this product when compared to ECC, there may still be some. I need to understand how will the configuration and any customization be moved between the systems of TEST and PRODUCTION? In ECC we have the mechanism of transport requests. What is the way to move configurations and customizations if any for S/4 HANA Cloud? Please advise.
