WACKER’s New Purchasing System
The Future of Purchasing Is Here
"Both suppliers and WACKER will benefit from the digitalization initiative, paving the way for future collaboration."
Dr. Kirill Rachinskiy - Director Services & Processes - Procurement & Logistics

Our aim is to establish efficient, interactive and above all sustainable procurement and purchasing processes using novel digital solutions. And we want to take this path together with our strong suppliers and service partners.
To do so, we will be expanding our SAP® Ariba® network with your active support and assistance on this joint journey. We expect from our partners that they:
- Sign up for WACKER’s SAP® Ariba® network or update your existing account
- Actively use the Ariba® network for tender and contract documents, as well as collaborate on supplier-management activities, such as exchanging data and documents with WACKER
- Use the Ariba® network’s integration options to successfully and efficiently conduct other procurement activities with this tool

Are you interested in starting or continuing a business relationship with WACKER? Then you need a free Ariba® network account. This interface enables you to exchange information and documents with us and participate in procurement activities.
The Ariba® Network offers you many advantages:
- Minimal effort: quickly and easily update and maintain required data or changes
- Full transparency: a central interface offers an overview of all relevant processes, including status information on procurement, contract and purchasing activities or supplier-management processes such as for certificates, etc.
- No fees: quickly and easily sign-up for a free standard account
Our partners need to take the following steps for the SAP® Ariba® platform’s onboarding process:
Step 1: Choose whether to create a standard or enterprise account
Step 2: Create an Ariba® Network account or login with your existing company account
Step 3: Fill out and submit WACKER’s registration & certificate management questionnaires
We expect our suppliers to sign up for the Ariba® Network.

SAP® Ariba® enables the exchange of purchase orders, order confirmations, order changes, shipping notifications, goods receipts, and the electronic processing of invoices and credit notes. To use this preferred interface with WACKER in the future, our partners need an Ariba® Network account.
Please refer to the “Onboarding process for our suppliers” section to learn more about Ariba® Network accounts and the process.
This solution offers an easily scalable EDI/WebEDI platform for optimizing the ordering and e-invoicing process and is therefore also attractive for mid-sized and smaller suppliers as a cost-neutral connection option.
The introduction will be implemented in different waves, in which we will proactively approach the selected suppliers to set up an extended business relationship with the help of Ariba®. We will inform our partners in advance via email.
For order processing, we will expect our partners to provide the following messages:
- Order confirmation
- eASN (electronic Advanced Shipping Notification)
- eASN reference barcode
The reference barcode is necessary for our incoming goods department, so that the system can allocate the goods received to an eASN.
Our partners must carry out the following order-processing steps:
Step 1: Decide whether you want to create a standard or enterprise account. WACKER considers a free standard account to be entirely sufficient. With the enterprise account, you can boost your internal efficiency (sales administration, accounting) by automatically transferring documents to your ERP system.
Step 2: Provide order confirmations and eASN or shipping notification
