Using SAP SRM
SAP SRM is used by those responsible for internal procurement.
* Employee-driven self-service, whereby employees are empowered to procure materials and services necessary to the completion of their organization's goals. Administration and processing are accomplished through one interface using web-based tools that not only make the process a simple one, but also facilitate corporate spending and procurement compliance.
* Automated materials procurement performed as part of an organization's supply-chain workflow (essentially integrating your purchasing function with your supply chain management system).
