SAP Ariba - Configuring SAP ERP

SAP Business Suite can connect to Ariba network using non-modifying add-ons that come with Ariba Network integration 1.0. Using these add-ons, you can send or receive message in the format supported by SAP Ariba- cXML.

With the use of Ariba add-ons, you can integrate single SAP ERP system or multiple systems with Ariba network. Integration can be performed directly or by using a middleware. One of the common integration options comes with the use of HANA Cloud Integration (HCI). With Ariba Network integration 1.0, following Business suites can be connected to Ariba network −

SAP ERP

SAP Suppper Relationship Management

SAP Supply Network Collaboration SNC

Following are the benefits of using Ariba Network Integration 1.0 −

You do not require an additional infrastructure or system to connect with SAP Business Suite.

Ariba Network Integration supports minimum SAP ERP 6.0.

With the use of Ariba add-ons, the network complexity is removed.

It does not require any upgrade, update to be performed.

Ariba Network integrations should be deployed on every ERP system that you want to integrate.

Product Requirement for Integration

In this section, we will look into the product requirement for integration.

Different Ways of Integration

Ariba integration tool kit is a Java based tool which can be used to upload master data or download transaction data from the SAP ERP system. With Ariba integration tool kit, it reads CSV files, zips the files and sends them as MIME messages to Ariba procurement solution using HTTP. Integration can be done with the following ways −

File based integration

Web services based integration

Direct Connectivity

Using Middleware connectivity

File-based integration

You can move master and transactional data from SAP to Ariba system using file-based integration. Master data extracted from SAP in the form of .csv files. These .csv files are transferred to Ariba system using Ariba Tool kit.

The following illustration shows file based integration and master data import to Ariba.

Follow these steps for transfer of transactional data from SAP to Ariba using the file-based integration method −

In the first step, the data transfer tool exports data from Ariba procurement solution in the form of *.csv files.

Ariba provided ABAP program then reads these *.csv files and transfers data to SAP ERP.

ABAP program then retrieves the status of each export transaction from SAP ERP.

The data transfer tool reads these *.csv files and updates them into Ariba.

Web service based integration

This is used to perform real time integration of Ariba to SAP ERP using SAP PI and this integration option is available by default. If you use any other middleware pke SOA, you will require configuring the setup manually. In Web service-based integration, a SOAP message is generated based on the WSDL and this is dispatched to a web services server using SAP Process Integration PI.

Integration using direct connectivity

With direct integration, .csv files are moved from SAP ERP to Ariba system. The .CSV files with master data is sent to Ariba system in the form of SOAP message. The direct integration option for master data is available from Ariba cloud integration 4.0 or later and transactional data integration is available from 6.0 or later.

Mediated connectivity integration

Mediated connectivity integration is available in Ariba Cloud integration 5.0 or later and the movement of transactional data from 6.0 or later. The mediated connectivity integration method can be used with SAP PI to exchange file data or by sending information as SOAP message.

When you use SAP PI for integration, you need to define receiver and sender communication channel. Note that SAP Ariba provides an Ariba Network Adapter for SAP PI/PO integration and is known as add-on module for SAP business apppcations that allows to send and receive document in cXML format to and from Ariba Network. By following Ariba SN cXML standards, it is also possible to develop own network adapters instead of buying a commercial one.
