Functional Overview

A receipt is an acknowledgment of the goods that have arrived. The receiving process starts when an order has been sent to a supplier and the supplier ships goods in exchange. When the shipment arrives, the person who receives those items, submits a receipt to acknowledge that the items have indeed arrived.

Negative receipt can also be created in Ariba Guided Buying to reverse some received quantity because of incorrect shipment or manual errors.

This document describes S/4HANA System inbound interface for sending goods receipt information from Ariba Guided Buying to S/4HANA System for POs received in Ariba Guided Buying. Goods receipt data from Ariba Guided Buying will be exported to S/4HANA System via SAP Integration Suite, Managed Gateway for Spend Management and SAP Business Network (formerly known as Cloud Integration Gateway) and loaded in S/4HANA as GR material document. 

Buyers using the Ariba Guided Buying integrated with S/4HANA System can create receipts using a standard SAP delivered Business Application Programming Interface (BAPI).

The following steps explain how a receipt export integration event works:

1. When Buyer creates a receipt in Ariba Guided Buying, the receipt will go to approval flow based on requirements.
2. When the receipt is fully approved, a copy is sent to S/4HANA System via SAP Integration Suite, Managed Gateway for Spend Management and SAP Business Network (formerly known as Cloud Integration Gateway (CIG)) and the respective Receipt status is then sent back to Ariba Guided Buying.
3. The RFC returns a receipt line number and any error information to Ariba Guided Buying.

The format of the messages that are sent through the web services from Ariba Buying to S/4HANA System and the format of the expected responses from S/4HANA System are defined in WSDL files (Web Service Description Language). These files furthermore contain details about the web service end points like URLs and port numbers.

The export of data through web services is always initiated by Ariba Buying. Once a transaction has been completed in Ariba Buying, it immediately sends out a SOAP message to the configured web service end point.

The CIG transforms that SOAP message and passes the data from that message in the right format to the S/4HANA System backend. The S/4HANA System then returns either a success or error message (including error details) to the CIG. This reply from the S/4HANA System is finally sent back to Ariba Guided Buying as SOAP message through web services.

Ariba web services are only used for exporting transactional data from the Ariba Guided Buying and sending it (via CIG) to the corresponding S/4HANA System.

Scope and Objectives

. The following Receipt web service integration events will be used:

• Export Receipts Asynchronously

There will be no scheduled task of data transmission as data is transferred in real-time.  Each submission of transactional data from Ariba Buying to the S/4HANA System requires a response from the receiving S/4HANA system that the data was successfully received and imported, or details about the error that occurred during the import. The receipts are being exported to S/4HANA with this event and the CIG document type is- ReceiptExportRequest. 

Process Flow Diagram

Assumptions

• Ariba Guided Buying is utilized for integration of Goods Receipts and SES with S/4HANA System.
• Ariba tolerance settings for under and over-receiving are synchronized with S/4HANA System.
• Ariba source object and S/4HANA System target field mappings, including custom fields, will be updated based on mapping requirements in S/4HANA System.

Dependencies

• All configurations should already be implemented before the interface is deployed.
• Ariba Buying packages have been successfully installed and configured in S/4HANA System.
• The connection information for Web-Services based integration have been successfully configured in Ariba Buying.
• Receiving feature is enabled in Ariba Guided Buying.
• Receiving parameters have been configured in Ariba Guided Buying.
• Master data loaded in Ariba Guided Buying is synchronized with S/4HANA System.
• Users need to be part of Field Service Administration group to force reject already processed Service Entry Sheet.

Security, Integrity and Controls

The following are the Security and Authorization considerations for this interface:

• Define a Web Services Security certificate and/or the shared secret key to use to secure the End Point connection.
• Access to interface parameters in Ariba Guided Buying are being addressed by Ariba standard security controls. Only authorized person with Ariba administrator’s role can access/ change interface parameters.
• Web service security configuration allows secure communications protocol provides a means for applying security to Web services.

Configuration Requirements

Ariba Configuration

Ariba Web Services enables exchange of data between Ariba Guided Buying and other systems, such as S/4HANA System, for real-time data integration.

Ariba Web Services provide integration tasks that send and receive SOAP messages for web services. An integration task requires an end point for the logical communication channel used by the web service. An end point consists of the URL and authentication information that controls access to the end point. There are two types of end points: inbound and outbound. Inbound end points are used when the task is initiated by the S/4HANA system. Outbound end points are used when the task is initiated by the Ariba Guided Buying.

Here, the Web Services channel provides real-time integration of Ariba Buying with S/4HANA system using SAP Integration Suite, Managed Gateway for Spend Management and SAP Business Network.

The following table lists operations for the integration tasks and end point types needed:

Interface Reporting

There are no specific reporting requirements. Ariba Buying analytical reports give users access to information from multiple sources, such as purchase orders, requisitions and receipts. Reports display data from these sources on a pivot table, which users can manipulate to see different scenarios for the data. Pivot tables allow users to filter, slice, and drill down into the information as needed to see broad patterns and relationships, summary information, and detail at the same time.

Ariba Buying includes a set of pre-packaged reports designed to help analyse the organization’s procurement and activities.

Performance Consideration

Error Handling

The S/4HANA System integration provides reliable data exchange between Ariba Guided Buying through CIG. However, in some cases, the integration event on the Ariba Guided Buying cannot recover automatically and must report the error to the appropriate administrator. When an error occurs, the integration event on the Ariba Buying System does the following:

• Recover automatically
• Report the error and wait for an administrator to take action

Here, if any errors occur for Goods Receipt or SES, the instance goes into “Rejected” state and the buyers are being requested to create another instance.
