ZFlow includes a sophisticated SAP adapter based on JCo (SAP’s Java connector library) that can be used to connect ZFlow workflows and objects to SAP BAPIs and RFCs. ZFlow can be connected to multiple Netweaver based SAP systems and often within the same workflow. This makes ZFlow ideal for process orchestration with SAP for many scenarios.
Connecting to SAP requires SAP JCO library that can be downloaded from SAP Support Portal.
