BPM OData Service (Enhanced)
The BPM OData service provides more uniform resource identifiers (URIs) to support additional access to BPM processes and tasks.
The BPM OData service enables you to get information about a process instance and an active process definition.
It also enables you to access substitution rules and comments of BPM tasks. If you want to enable or take over a substitution rule, the BPM OData service provides the EnableSubstitutionRule operation.
