Parameters

Optional Parameters
NameValue TypeDescription
interactionFilter string
Name of a predefined user interaction.
ValueDescription
CREATE
Create tasks. This implies the retrieval of collaboration and invocation task templates permitting the instantiation of corresponding task instances. This value requires that a query table is used where TASK_TEMPL is the primary query table and TASK_TEMPL.KIND and TASK_TEMPL.STATE are provided as source attributes.
selectedAttributes string
Comma-separated list of attributes, in uppercase letters, which specifies the attributes that are retrieved by the query. If no selected attributes are specified, all the attributes that are defined on the query table are returned.
queryFilter string
A query table condition language expression that performs additional filtering on the result set. All attributes defined on the query table can be referenced. Constants are available for some attributes of predefined query tables, for example, STATE_STARTED is available for attribute STATE on query table TASK_TEMPL (for available constants, see [BPC DB Views]).
processAppName string
Name of the process application, which is used for additional filtering.
sortAttributes string
Comma-separated list of sort criteria applied to the list of returned task template entities. Each list entry is in the form attribute [ASC|DESC] where ascending is the default.
offset integer
Specifies the number of entities to be skipped in the result set.
size integer
Limits the number of entities returned. The threshold setting might not be accurate.
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.
false (default)
