Did you include retry mechanisms in your SAP integrations? How did you ensure that SAP did not lose data?

In SAP integrations, retry mechanisms are usually implemented to ensure reliable data transfer during temporary network or service failures. Message queues (e.g., RabbitMQ, Kafka) or built-in SAP PI/PO mechanisms are often used for guaranteed delivery.

To prevent data loss in SAP, the following approaches are applied:

• Idempotency of operations: resending the same message does not lead to data duplication.
• Logging and monitoring: all sending attempts and their results are recorded.
• Use of transactions and acknowledgments: SAP confirms receipt and processing of data, only then is the message considered successfully delivered.

An example of a simple retry at the integration service level in JavaScript:

async function sendToSAP(data) {
  const maxRetries = 3;
  let attempt = 0;
  while (attempt < maxRetries) {
    try {
      await sapApi.send(data);
      return true; // success
    } catch (err) {
      attempt++;
      if (attempt === maxRetries) throw err;
      await delay(1000 * attempt); // exponential backoff
    }
  }
}
