Protect SAP S/4HANA dialog work processes and BTP services from abusive consumers and traffic spikes. Generate ABAP Cloud Token Bucket limiters, HTTP 429 response headers, and SAP API Management XML policies.
Master traffic shaping, circuit breakers, and zero-downtime extensibility in The SAP Clean Core & ABAP Cloud Handbook.
Unregulated API traffic consumes SAP dialog (DIA) processes, causing core ERP timeouts. In-memory token bucket checks reject excessive requests in sub-milliseconds before database hits.
Provide standardized RateLimit-Limit, RateLimit-Remaining, and Retry-After headers. Downstream callers automatically throttle back without crashing.
For maximum core protection, deploy Spike Arrest and Quota policies on SAP API Management at the BTP perimeter, discarding rogue traffic before it traverses Cloud Connector.
