The SAP Basis Plug-In is a new software component that provides SAP components with BW service API technology as well as functions from CRM Middleware, Supply Chain Event Management, and Financial Basis to establish a connection to these systems.

The SAP Basis Plug-In is an Add-On that you can install on a SAP Web Application Server or on another product that is based on SAP BASIS 620 and SAP ABA 620 or higher releases of these software components.

Within SAP R/3 Enterprise, the SAP Basis Plug-In is a prerequisite for the SAP R/3 Plug-In. The SAP Basis Plug-In and the SAP R/3 Plug-In must always have the same release level, for example, PI 2004.1 and PI Basis 2004.1. When you are planning an upgrade for the SAP R/3 Plug-In within SAP R/3 Enterprise, you must also upgrade the SAP Basis Plug-In as well. As of SAP Basis Plug-In 2005.1, the release level of the two Plug-Ins no longer has to be the same. However, the SAP R/3 Plug-In Support Package for PI 2004.1, which contains new interfaces, still requires a particular SAP Basis Plug-In. For example, SAP R/3 Plug-In Support Package 10 for SAP Plug-In 2004.1 requires the SAP Basis Plug-In 2005.1 .

You only need to upgrade the SAP Basis Plug-In in one system within your system landscape and you can then use the available SAP Basis Plug-In release in all the other systems within the system landscape.

The release PIB 2004.1 Workplace Plug-In is part of the SAP Basis Plug-In for SAP Basis 640.

The SAP Basis Plug-In is downward compatible and has the same release and maintenance strategy as the SAP R/3 Plug-In. SAP delivers it together with the SAP R/3 Plug-In. For more information, see SAP Service Marketplace at  service.sap.com/basis-plug-in SAP Plug-In SAP Basis Plug-In Releases.
