To integrate an SAP Business Workflow (BWF) system for use with Task Gateway, you must verify that your system is set up appropriately (prerequisites are fulfilled). Note that the SAP Business Workflow system must be based on SAP NetWeaver 7.00 SPS18 or higher. You must install the component IW_BEP in your SAP Business Workflow system. If your system landscape is based on SAP NetWeaver 7.40 or higher, it contains the core SAP Gateway component SAP_GWFND as standard and, as such, you do not need to install IW_BEP in your SAP Business Workflow system.
