Guides for suppliers

By collaborating electronically and pushing for new methods for conducting sourcing activities, we work towards the goal of increasing efficiency in our tender process. That is why we expect our suppliers to:

• respond to RFIs, RFPs and e-Auctions only through SAP Ariba and to carefully go through requirements and specifications stated in the tender invitations prior to participation.

If help is needed in order to meet these expectations, we kindly ask our suppliers to first seek help in the technical guides provided below.
