Prerequisites

To assign tasks correctly, you must make sure you have the needed folder permissions set in Orchestrator. The Folder Permissions for the Robot role in Orchestrator must have the Create permission enabled.

Windows-Legacy, Windows configuration

Designer panel
  • Assignment criteria - Enables you to assign the action to:
    • A Single User: assign the action to a specific user.
    • All users in a group: assign the action to all users in a certain group.
    • Workload based: assign the action to the user in a specific group who has the least workload.

    See Group assigning Actions for more details.

  • Single task assignment

    • Task Id - The ID of the task.
    • User Name or Email - The username or email address of the user that you want to assign this task to.
    • Task Assignment Type - The type of the assignment operation to be performed. By default, the Assign operation is set, and it can be changed to Reassign if you want to assign the same action to a different user.
    • TaskUserAssignments - A list of task identifiers and corresponding user information to which an action is to be assigned/reassigned, stored in a List<TaskUserAssignment> object. This field supports List<TaskUserAssignment> objects only. The object must contain a task identifier and its corresponding user information, such as an email address or a username that is registered in Orchestrator.
    • FailedTaskAssignments - If any of the user assignment requests fail, a list is created, containing the task identifier, error message, and error code, as well as the email address or username that is registered in Orchestrator, in a List<TaskAssignmentResponse> object in this property field. This field supports List<TaskAssignmentResponse> objects only.

    Multiple task assignment

    Select Enable Multiple Assignments. The following properties are available in the designer panel:

    • TaskUserAssignments (Input) - A list of task identifiers and corresponding user information to which an action is to be assigned/reassigned, stored in a List<TaskUserAssignment> object. This field supports List<TaskUserAssignment> objects only. The object must contain a task identifier and its corresponding user information, such as an email address or a username that is registered in Orchestrator.
    • Task Assignment Type - The type of the assignment operation to be performed. By default, the Assign operation is set, and it can be changed to Reassign if you want to assign the same action to a different user.
    • FailedTaskAssignments - If any of the user assignment requests fail, a list is created, containing the task identifier, error message, and error code, as well as the email address or username that is registered in Orchestrator, in a List<TaskAssignmentResponse> object in this property field. This field supports List<TaskAssignmentResponse> objects only.
  • Enable Multiple Assignments - Enables the option to assign multiple tasks.
  • Task Id - The ID of the task.
  • User Name or Email - The username or email address of the user that you want to assign this task to.
  • Task Assignment Type - The type of the assignment operation to be performed. By default, the Assign operation is set, and it can be changed to Reassign if you want to assign the same action to a different user.

Properties panel

Input

  • Orchestrator Folder Path - The path to the Orchestrator folder you want to use with this activity. If left empty, the current Orchestrator folder is used. This field supports only strings and String variables.

Misc

  • ContinueOnError - Specifies if the automation should continue even when the activity throws an error. This field only supports Boolean values (True, False). The default value is False. As a result, if the field is blank and an error is thrown, the execution of the project stops. If the value is set to True, the execution of the project continues regardless of any error.

    If you include the AssignTasks activity in a Try Catch activity and the value and the value of the ContinueOnError property is True, no error is caught when the project is executed.

  • TimeoutMS - Specifies the amount of time (in milliseconds) to wait for the activity to run before an error is thrown. The default value is 30000 milliseconds (30 seconds).

Cross-platform configuration
