Theobald Software GmbH is finally releasing an existing new product to integrate SAP business data into SharePoint 2010. ERPConnect Services is its name and consists of 3 components, which allow you the complete range of data integration between SharePoint and your SAP ERP/BW system.
ERPConnect Services also gives you the opportunity to realize Single-Sign-On scenarios: Using the SharePoint Secure Stores, users can access SAP with their personal SAP credentials. While doing so, all SAP safety guidelines will be available directly in SharePoint.
