A repeated request should not create an unwanted repeated transaction. Design identifiers, duplicate handling and reconciliation into SAP integrations.
Distinguish a message from its effect
An integration can time out after the receiving system has completed an operation. Retrying blindly may create another order, posting or update. Define which business actions must be protected from duplicate execution.
Use stable identifiers that represent the intended operation. A fresh random identifier on every retry defeats a duplicate-detection design.
Define the duplicate response
SAP documents idempotent-process-call behavior for integration flows. Review the exact capabilities of your environment and decide how a previously completed operation should be reported. The caller needs to distinguish a harmless duplicate from a genuinely failed transaction.
Keep retention and reconciliation requirements in mind. A duplicate check with insufficient history may not protect a delayed replay.
Test uncertain outcomes
Simulate lost responses, repeated deliveries and partially completed workflows. Confirm that downstream systems and support staff can understand the resulting state. Avoid treating exactly-once behavior as a universal promise across every boundary. The practical goal is a reliable business outcome with a clear recovery process.
A practical next step
- Identify duplicate-sensitive business operations.
- Reuse operation identifiers during retries.
- Define the response for an already completed action.
- Test replay and uncertain-result scenarios.
