The SAP Business Network enhances a business’s ability to manage complex, multi-party interactions in a seamless, integrated environment, promoting transparency, efficiency, and collaboration across industries. Understanding and maintaining the required parameters within the SAP system is crucial to ensuring the invoice integration functions effectively. In the Managed Gateway-AddOn, parameters are used to configure and manage how invoices are transmitted from the SAP Business Network to SAP ERP or S/4HANA (on-premise).
Maintaining parameters for invoices in the Managed Gateway-AddOn is essential for ensuring a smooth, secure, and business-aligned exchange of invoice data between the SAP Business Network (Ariba) and the SAP system. Proper parameter settings eliminate manual checks and enable touchless invoice processing. Parameters act as configuration switches that define how invoice data is processed, validated, and transformed. They allow you to tailor the integration to fit your organization’s business processes, such as enabling Ariba-specific enhancements, parking invoices, handling non-PO credit memos or non-PO invoices, etc.
You can maintain the parameters based on your requirements. Most of the parameters are optional and need to be maintained as necessary. However, the INVOICE_ENABLED parameter is mandatory when you enable integration using the Managed Gateway.
Follow these steps to maintain the parameters for the Invoice in the Managed Gateway AddOn SPRO:
Using the transaction code SPRO, navigate to Integration with Other SAP Components>Managed Gateway for Spend&Network for Buyer>SAP Business Network Integration>Application Specific Settings>Invoice.

- Expand the Invoice section and select IMG-Activity for Maintain Parameters for Invoice.

- On the Parameters – Invoice screen, select the Modify button.

- On the Parameters – Invoice screen, maintain the parameters based on your business requirements.
- Once all the necessary entries are maintained, select the Save button.
