SAP Supplier Relationship Management (SAP SRM) enables you to link suppliers to your purchasing processes via the SAP Supplier Network or through the supplier portal. With SAP SRM, you can choose the optimal interaction channel for numerous business processes and documents, and you can collaborate more effectively with suppliers in supplier-facing processes in the following areas:

• Document exchange – Exchange any document in any format smoothly across heterogeneous systems through general-purpose adapters that facilitate messaging between SAP and non-SAP systems - both internally and externally.
• Supplier portal management – Give suppliers direct access to their customers' SAP and non-SAP applications through content provided by a suite of Web-enabled services. Provide the pre-assembled content on the SAP supplier portal for collaboration.
• Supplier collaboration – Collaborate with suppliers throughout the life cycle and make integration with suppliers of all sizes economical and easy to manage. With SAP SRM's supplier self-services, suppliers can access supply-side transactions and other relevant information and update their catalog data, process acknowledgements, track payment status, suggest changes to orders, and receive information on inventory and supply-and-demand plans.
