I believe the SRM solution and E-sourcing (SAP re-branded SAP Sourcing- xCLM/ESO..) are still separated by the border line - Collaborative sourcing.
E-sourcing offers the collaborative sourcing activities. SRM offers the Purchase order execution collaboration (with PLM).
One of the classical integration is SRM talks (create Electronic Requirement) to ERP (SAP ECC as Purchase Requisition) and ERP talks E-sourcing (and carries out the sourcing requirement).
