Exception handling and monitoring

An exception path should preserve useful evidence and the correct failure outcome. Catching an exception and returning a success-shaped response can stop recovery while losing a business message. Correlation connects flow observations to receiver evidence without requiring permanent full-payload logging.
Visual overview
Explanation
Tutorial outcome
An exception path should preserve useful evidence and the correct failure outcome. Catching an exception and returning a success-shaped response can stop recovery while losing a business message. Correlation connects flow observations to receiver evidence without requiring permanent full-payload logging.
Prerequisites
Complete chapters 1–8 in this module. Use synthetic fixtures or an authorized sandbox.
Worked case — fictional
A fictional flow catches a receiver rejection and returns a misleading success to the sender.
Step-by-step investigation
1. Reproduce
Use a synthetic invalid order and record the receiver's business rejection.
Expected evidence: ORD501 fails required-field validation.
2. Correlate
Connect sender, message-processing and receiver identifiers using sanitized metadata.
Expected evidence: Correlation C501 appears across the evidence set.
3. Handle
Choose an error response or controlled recovery path that matches the sender contract.
Expected evidence: The sender receives the defined failed outcome.
4. Verify
Check that the message is not simultaneously reported as posted and queued for uncontrolled retry.
Expected evidence: Status and recovery owner agree on the failure.
Try it yourself
Reproduce the synthetic input from the example below in a local fixture or authorized sandbox. Follow each step, record the observed result, and explain any mismatch before continuing. Do not treat the expected evidence as a result observed in your SAP tenant.
Acceptance check
Invalid business data remains a visible failed case with a named correction owner.
Common failure to avoid
Do not convert every exception to success or retry a schema error indefinitely.
Self-check
What can go wrong if every exception returns success?
Expected reasoning: The sender may stop recovery even though no business result exists.

Real project scenario
A fictional flow catches a receiver rejection and returns a misleading success to the sender.
Common mistakes
Do not convert every exception to success or retry a schema error indefinitely.

Interview angle
What can go wrong if every exception returns success? The sender may stop recovery even though no business result exists.

1. What is the purpose of an exception subprocess in an iFlow?
2. Where do you see the status and log of processed messages?
3. Why avoid logging full payloads in production by default?
Interview questions
1. How do you design error handling and monitoring for an iFlow?
Answer it in your own words first, then compare.
2. An interface fails silently — the sender thinks it worked. How do you prevent this?
Answer it in your own words first, then compare.
