Shared people assignments
For a specific task role, the same people assignment criteria are used in all instances of a task template. This is because all of the task instances are instantiated from the same task template. To avoid rerunning people queries, the result of a query is shared across task instances of a task template.
The sharing of results applies only if a people assignment criteria definition contains fixed parameter values. Such values, for example, the name of a group: cn=group1, cn=groups, imply that the corresponding people query result is the same, regardless of the task instance context in which the people query is resolved.
If the people assignment criteria definition contains replacement variables, the sharing scope is reduced to people assignments that have the same replacement variable values.
For example, a parameter value can depend on parts of the input message of a task. Because different task instances can have different input messages, the parameter values for the people queries differ, too.
If you post process people query results, sharing does not apply to these results by default. To enable the sharing of post-processed results in the administrative console:
- Click either Servers > Clusters > WebSphere application server clusters > cluster_name or Servers > Server Types > WebSphere application servers > server_name, then on the Configuration tab, in the Business Integration section, expand Business Process Choreographer, and click Human Task Manager.
- In the Additional Properties section, click Custom Properties and change the value of the Staff.PostProcessorPlugin.EnableResultSharing custom property to true, then save your changes
- Restart the server or cluster to make the changes effective.
