The OData Channel services provide a Workflow task service for the Business Workflow.
Depending on whether you use the Business Enablement Provisioning (BEP) functionality in an SAP Business Suite backend system or an SAP Gateway hub system, choose the appropriate service for your system landscape:
Workflow Task Service: Central Hub Deployment with IW_BEP Backend Installation
Workflow Task Service: Central Hub Deployment with IW_BEP Hub Installation
If your system landscape is based on SAP NetWeaver 7.40 or higher, you do not need to install the IW_BEP component in your system since the BEP functionality is included in the core SAP Gateway component SAP_GWFND, which is installed as standard.
For more information about setting up your system landscape, see Deployment Options.
