PI/PO sunsetting or integrations failing.Get a verified integration consultant in minutes.

Yes. PM scopes the migration approach in the first 15 minutes. SAP PI/PO mainstream maintenance ends in 2027 (extended to 2030 with the extension), so the consultant first inventories your existing PI/PO interfaces and classifies them by adapter type and complexity. They then plan the move to Cloud Integration (CPI) within SAP Integration Suite using the Migration Assessment and Migration Tooling, which converts a subset of PI/PO iFlows automatically. Interfaces that do not auto-convert custom adapter modules, complex BPM processes, or proprietary mappings are rebuilt natively in CPI as integration flows. The consultant maps PI adapter types to their CPI equivalents (IDoc, SOAP, REST, SFTP, JDBC, Mail), rebuilds message mappings, externalizes parameters for tenant promotion, and sets up monitoring. You leave the session with a migration backlog, effort estimate, and at least one interface fully migrated and tested as a reference pattern.

The consultant configures the IDoc adapter (or IDoc SOAP adapter) in Cloud Integration so your ECC or S/4 system continues sending IDocs without backend changes. On the SAP side they confirm the partner profiles (WE20), ports (WE21) pointing to the CPI endpoint, and RFC destinations or the SOAP/HTTPS connection are correct. In CPI they build the iFlow to receive the IDoc XML, apply message mapping to the target structure (for example IDoc to a third-party REST payload), handle the control record and acknowledgments (ALEAUD) so the sending system knows delivery status, and route by message type or partner. They add exception subprocesses for failed IDocs, configure retry and dead-letter handling, and set up the message monitor with alerting so failed IDocs surface immediately rather than silently. They reproduce a failing IDoc, fix it, and reprocess it before closing.

Yes. The consultant builds both inbound and outbound integrations in Cloud Integration and, where appropriate, exposes managed APIs through API Management within Integration Suite. For REST they configure the HTTP/REST adapter, handle OAuth2 (client credentials, authorization code), API keys or certificate-based authentication stored in Security Material, and parse/transform JSON payloads using message mappings or Groovy/JavaScript scripts. For SOAP they configure the SOAP adapter with the partner WSDL, handle WS-Security and SOAP headers, and map between SAP structures and the external schema. They implement proper error handling, idempotency where the target is not idempotent, pagination for large result sets, and rate-limit-aware retry logic. If you need to publish your own APIs to partners, they use API Management to add policies for authentication, rate limiting, and payload validation, plus a developer portal so consumers can self-onboard.

PM treats intermittent failures as an incident. The consultant starts in the Cloud Integration message monitor, filtering by failed and retried messages to find the pattern is it time-based (token expiry), volume-based (target throttling), or payload-based (a specific message structure)? They enable trace-level logging on the suspect iFlow temporarily to capture the exact payload and step where it fails, inspect the Message Processing Log, and check the Security Material for expiring credentials. Common intermittent causes they fix: OAuth tokens expiring without refresh, the target system rate-limiting under load, missing exception subprocesses so transient errors are not retried, connection pool exhaustion, and timeouts set too aggressively. The fix typically adds robust retry with exponential backoff, externalized timeouts, token caching/refresh, and alerting through the Alert Notification service so the next failure is caught proactively, not by an angry user.

The consultant sets up a disciplined transport process so iFlows move cleanly without manual rework. They externalize every environment-specific value (endpoints, credentials, queue names, parameters) into externalized parameters and Security Material rather than hardcoding them, so the same package promotes across tenants by only swapping configuration. For transport they use the Content Transport feature with the Cloud Transport Management Service (cTMS) or the MTAR/CTS+ route, depending on your landscape, to move integration packages from dev to test to prod with an audit trail and approval gates. They establish naming conventions and package structure, version control through the Integration Suite Git integration where available, and a release checklist. They also configure value mappings and partner directory entries per tenant. The result is repeatable, auditable promotions instead of error-prone manual copying between tenants.
