ERP Integration Services: How to Prevent Duplicate and Failed Transactions

Before sending another transaction into the ERP, the workflow should determine whether that event has already been processed.

If order 58421 has already created ERP order 90732, the integration should know that relationship.

When the source sends order 58421 again, the workflow can inspect its prior state instead of creating another order automatically.

The correct response may be to ignore the duplicate event, process an approved update, or place the record into an exception queue for review.

This is more reliable than simply comparing dates, amounts, or customer names because two legitimate transactions can contain similar values.

Transaction identity should come from the actual source event and its processing history.

Make ERP Retries Safe

Retries are necessary because integrations operate across systems that can temporarily fail.

An API may time out. A database can become unavailable. An ERP endpoint may reject requests temporarily. Credentials may need to be renewed.

The goal should not be to eliminate retries. It should be to make them safe.

An ERP workflow should avoid repeating steps that already completed successfully.

If a five-step process fails at step four, restarting everything from step one may recreate records that already exist.
