ERP Integration Services: How to Prevent Duplicate and Failed Transactions

One of the most important integration controls is understanding the difference between a confirmed failure and an unknown result.

A confirmed failure means the ERP clearly rejected the request.

Perhaps a product does not exist, a location is inactive, or a required field is missing.

An unknown transaction is different.

The integration may have sent the request but lost communication before learning whether the ERP processed it.

Automatically retrying an unknown transaction can create duplicates.

Instead, the workflow should preserve enough information to check the ERP destination before deciding whether another creation attempt is appropriate.

This is why integration logs alone are not enough. The workflow should understand the business record that was supposed to exist in the destination.

Control Multi-Step ERP Workflows

ERP integrations often involve more than one action.

Consider an e-commerce order.

The workflow may create or identify the customer, create the order, update inventory, send fulfillment information, create an invoice, record payment information, and return shipment or order status to another system.
