You can consume Workflow tasks in system landscapes that include the BEP functionality.
This service requires the BEP functionality in
SAP Gateway hub systems
only.
Note If your system landscape is based on SAP NetWeaver 7.4 or higher, you do
not need to install the component IW_BEP
since the BEP functionality is included in the core Gateway component
SAP_GWFND, which is installed as
standard.
