Parameters

Required Federation Parameter
NameValue TypeDescription
domain string Name of the domain containing the BPEL runtime systems that host the distributed resource (mutually exclusive with the systemID parameter).
systemID string ID of the BPEL runtime system hosting the resource (mutually exclusive with the domain parameter). If specified then this request is treated like any other request for a resource hosted by a single system, that is, the request and the response are just routed, and no pre/post-processing of parameters and results is performed by the federation layer.
Optional Parameters
NameValue TypeDescription
queryFilter string
A query table condition language expression that performs additional filtering on the result set. All attributes defined on the query can be referenced.
processAppName string
Name of the process application, which is used for additional filtering.
everybody boolean
Authorization option specifying that everybody work items (which is the staff verb "Everybody") are taken into account if instance-based authorization is enabled on the query table. This parameter has no default. If it is omitted then the settings of the query table definition apply.
individual boolean
Authorization option specifying that individual work items, for example, the staff verb "Users", are considered if enabled on the query table. This parameter has no default. If it is omitted then the settings of the query table definition apply.
group boolean
Authorization option specifying that group work items, for example, the staff verb "Group", are taken into account if instance-based authorization is enabled on the query table and if enabled on the Human Task Container. This parameter has no default. If it is omitted then the settings of the query table definition apply.
inherited boolean
Authorization option specifying that inherited work items are considered, for instance, the administrator of a process instance might then see participating human task instances created for that process instance if it executes a query against that query table. This parameter has no default. If it is omitted then the settings of the query table definition apply.
admin boolean
Administration authorization option specifying whether the request is performed by an administrator.
ValueDescription
true
The request is performed by an administrator. The user must have administrative rights to perform this request. If the onBehalfUser parameter is specified as well then the request is performed as if the specified user had sent the request, otherwise, the request runs as administrator.
false (default)
The request is performed by a regular user who doesn't have administrative rights.
onBehalfUser string
Administration authorization option specifying that the query is run under the authority of the specified user, and the objects in the query table are checked against the work items for this user if instance-based authorization is used. This parameter is only valid if the admin parameter has been specified with a value true. If admin is set true and this parameter is not used then the request runs as administrator.
