SAP Process Orchestration provides user-friendly monitoring and central logging, seamless integration with backend systems using diverse adapters, and supports extensive partner integrations. Though setup is straightforward with low licensing costs, technical support responsiveness needs enhancement. It requires improved cloud scalability, more pre-delivered content, and better API capabilities. Upgrades cause downtime, and it struggles with high data volume. Monitoring should be less technical for business users, ensuring stability and low maintainability efforts.
