Introduction
The scope item Automation of Source-to-Pay with Ariba Network (42K), lets you as a purchasing expert or an accounts payable accountant focus on value-driven activities with SAP Ariba Commerce Automation integration with your suppliers in the Ariba Network, and drive productivity with nearly touchless orders and invoices. Since payment is integrated, you can pay your suppliers automatically.

Automation of purchase order to payment processing in the Ariba Network with SAP Ariba Commerce Automation integration enables you to connect seamlessly from SAP S/4HANA to your suppliers in the Ariba Network. You can send them requests for quotations, asking them for price and quantity information, as well as for shipping costs. You can also send electronic purchase orders and goods receipts to your suppliers using the Ariba Network, and you can receive electronic order confirmations for materials, advanced shipping notifications, and invoices in SAP S/4HANA Cloud from your suppliers. You can use Ariba Network integration in the procurement of direct or indirect materials and in the procurement of project-based services processes. You can also send payment advice in electronic form to your suppliers in Ariba Network. All data is routed through the SAP Integration Suite, managed gateway for spend management and SAP Business Network (Managed Gateway for Spend&Network).
Digitized collaboration with your suppliers in the Ariba Network supports you in speeding up procurement to payment processes and in reducing the number of manual process steps, reducing the cost of transactions with your suppliers.

General Notes and Restrictions
The scope item, Automation of Source-to-Pay with Ariba Network (42K), is intended to cover the same business processes as its predecessor Automated Purchase-to-Pay with SAP Ariba Commerce Automation (J82). Since Automation of Source-to-Pay with Ariba Network (42K) leverages the advantages of the Managed Gateway for Spend&Network, please do not implement Automated Purchase-to-Pay with SAP Ariba Commerce Automation (J82) as of now. Existing implementations of Automated Purchase-to-Pay with SAP Ariba Commerce Automation (J82) can still be used until further notice.
Within Automation of Source-to-Pay with Ariba Network (42K), the process Automated Purchase-to-Pay is currently different from its predecessor Automated Purchase-to-Pay with SAP Ariba Commerce Automation (J82) in the following aspects:
Only standard items, including lean service items, and enhanced limit items of product type group service are supported.
Note
Enhanced limits for material items are currently not supported.
Currently, you must not create purchase orders that contain both enhanced limit items and material items or lean service items. Some follow-on documents, such as purchase order confirmations, do not support this and will fail.
Currently, you cannot create purchase order confirmations for enhanced limits.
Lean service items and enhanced limit items require a service entry sheet as a follow-on document. This document is necessary to enable invoicing of the service or limit items. This means that purchasers must not clear theGR Indicator (goods receipt indicator) checkbox when creating a purchase order item for a lean service or for an enhanced limit.
Cancellation of service entry sheets is not supported. This also applies to service entry sheets for enhanced limit items.
Partial confirmations are not supported. You can only send confirmations for the entire purchase order, that is, for all material items.
Return items are not supported.
Attachments on item level are not supported. For inbound deliveries, no attachments are supported.
Integration with more than one buyer account on the Ariba Network is not supported.
Document status updates from the Ariba Network to SAP S/4HANA Cloud are not supported.
Customer-created fields cannot be mapped using the mapping tool in the Managed Gateway for Spend&Network.
For all functions, there are dependencies on your configuration settings in SAP S/4HANA Cloud and on your settings for the transaction rules on your buyer account on the Ariba Network. The transaction rule settings required for this scope item refine the restrictions further and may cause some additional restrictions. The transaction rules are described in the Setup Instructions. (You can find the guide in the Best Practices Explorer 42K).

- Streamline the process of service procurement in the Ariba Network.
- Create service PO in SAP S/4HANA Cloud and send it to suppliers in the Ariba Network.
- The service entry sheet is created by the supplier in the Ariba Network.
- Receive the service entry sheet and approve it in SAP S/4HANA Cloud.
Quick Enablement of Suppliers on the SAP Ariba Network

If quick enablement for suppliers is enabled in the Ariba Network, purchasers can now initiate trading relationships with new suppliers by adding them to a purchase order. When a purchase order for a new supplier is transferred, the Ariba Network automatically creates an account and sends an invitation e-mail to the supplier. When supplier registration is completed, the new supplier can access the Ariba Network and process the purchase order.
The following are the Restrictions:
Quick enablement can only be used for suppliers that exist in SAP S/4HANA.
Because invitations from the Ariba Network are always sent to suppliers by e-mail, quick enablement can only be used for suppliers with a valid e-mail address specified in SAP S/4HANA Cloud. No other communication methods are supported.
Additional Features
Automation of Source-to-Pay with Ariba Network (42K) supports the following features.
Support of price tolerance in purchase orders:
Offer purchase-order price-tolerance intervals to which suppliers must adhere in purchase-order confirmations
Enable suppliers to change the price in order confirmations if the price is within the price tolerances allowed
Further enhance collaboration with suppliers: buyers can add specific instructions and information for suppliers in a different header and item texts in purchase orders
Support price-basis quantity factors
Allow onboarding of new suppliers through quote automation by sending central RFQs to suppliers to initiate the onboarding process

You can use this app to create Requests for Quotations (RFQs) in SAP S/4HANA. There are different processes that you can start from within the Manage RFQs app:
You send your created RFQs later to SAP Ariba Sourcing, where the bidders and suppliers can place their bids. After you have decided which bidder or supplier should receive the award, you send the awarded quotation back to SAP S/4HANA. A purchase order or a contract is created automatically in the background. You can display it in the Manage Purchase Orders app or in the Manage Purchase Contracts app.
To request only price and quantity information or shipping costs, you send these RFQs later to the the Ariba Network, where the suppliers can create their bids. These bids are sent back to SAP S/4HANA, where you can award one of them.
You can also create price requests in SAP S/4HANA and send them directly to your supplier over e-mail or as a printed version by mail. You receive the quotations from your suppliers and then create the quotations in SAP S/4HANA manually.
Support of Lean Service Items in Request for Quotations with SAP Ariba Sourcing

Purchasers can now create a Request for Quotations (RFQ) by adding lean services along with goods in SAP S/4HANA Cloud through integration with SAP Ariba Sourcing. Purchasers can set a delivery range with a service start and end date for every service type of item.
- The purchaser can create an RFQ of type external sourcing request by adding lean service items and other items of type material.
- Strategic purchasers in SAP Ariba Sourcing can view the created sourcing request by searching with the reference of the RFQ ID and perform other sourcing-related activities as normal to finalize the bid and award.
- Send the quote to external system. This creates a supplier quotation and follow-on document like purchase order or purchase contract in SAP S/4HANA Cloud for the respective items of lean service and/or material type.
- The sourcing request in SAP Ariba Sourcing will include a delivery range for lean service items, which is visible to suppliers for bidding.
