Article summary

Task Panel

To configure a task on the new canvas, double-click a task on the Canvas to display information on that task in a panel on the right. Each Task panel will contain a Data, Advanced, and Details tab.

  • The Data tab contains input and output variables.
  • The Advanced tab contains the Access Control, Run Window, and Retry Task configurations.
  • The Details tab contains a description of the task that can be edited as well as a link to the API Documents page.

Tasks from the Canvas make calls to actions that perform specific and discreet activities to implement business logic. They take input arguments and return output variables. The inputs and outputs for the task are visible in the Edit dialog under the Incoming and Outgoing tabs (Figure 1) of the dialog. In the event an error occurs, the task may return an error variable, which is visible under Error.

Figure 1: Task Configuration Panel

Configuring Task Properties

Use the information presented in the following sections to configure a task.

Incoming Parameters

Task information is split between three tabs.

  • Data: Input variables for the task.
  • Advanced: Configurable options not directly related to input.
  • Details: The task description.

Figure 2: Task Parameters
02_Task Parameters_2023_1

Label UI Element Description
1 Incoming (Tab ) Required (mandatory) parameters are marked with an asterisk.
- Variable: The argument name.
- Type: Data type (boolean, string, number, array, object).
- Reference task: Defines the data source. Options include: job, static, a prior task.
- Reference variable: Value is assigned from the defined Reference task.
2 Actor
(for Automatic Tasks only)		 Execute automatic tasks by the system or a user by setting the Actor field.
-Itential (Pronghorn): The system executes the automatic task.
-job: Execute the automatic task as the user that started the job.
- Any previous manual task: Execute the automatic task as the user that worked a previous manual task.
3 Run Window Restrict when an automated task will run by specifying a schedule.
4 Description Enter a brief task description in the optional Description field.
Note:

Avoid changing to another task's input variable, which could create variable type mismatch and other errors.

Reference Task Options

Option Description
job A global variable. Job variables are set at the time a job is started or when a task's outgoing data is copied to a job variable. Job variables are visible to all tasks defined in the automation. Job variables are mutable. Some job variables are always present; others are defined by the collection of input job variables between all tasks in the automation.
static A constant; a value defined within the task properties.
any prior task Present in the current automation (listed by name in the dropdown).

Reference Variables

Reference Task Reference Variable
job Defaults to same name as the task's parameter. Dropdown shows all job variables, including input arguments for every task whose reference task is the job. To set a custom job variable name, click EDIT and type the new name in the Reference variable field. Job Variable names must adhere to the IAP Naming Conventions provided in the developer guide.
static Static value entered in Reference variable field.
a prior task Name of an output variable or error from selected prior task.

Manual Tasks & Access Control

For Manual tasks only, use Groups, located under the Advanced tab and in the Access Control drop down, to restrict who is authorized to work the task by assigning one or more groups.

  • Type "Administrators" in the Groups field. Matching group names will appear in a list after you begin typing.
  • Click the correct group name to add that group to the task's groups. The group will not be added unless it is selected from the list.
  • Add as many groups as desired.

Outgoing Parameters

Configurable options in the task output are referenced below (Figure 4).

Figure 4: Outgoing Tab
04_outgoing_2023_1

Label Ougoing Parameter Description
1 Variable The task's return variable; the variable which is made available to any subsequent task in the workflow. Outgoing variables are immutable.
2 Job Variables To promote the task's return variable to a job variable, check the Store Output as Job Variables box. This copies the outgoing variable's value to a job variable. Job variables are similar to global variables; they are available to every task in the job.
3 Job Variable Names Defaults to the same name as the task's return variable. To set a custom name for the return variable, type the new name in the Job Variable Name field. Job Variable names must adhere to IAP Naming Conventions.

Error Parameters

Task error variables are referenced below (Figure 5).

Figure 5: Error Tab
05_outgoing_Error_2023_1

Label Error Parameter Description
1 Variable The task's error variable, which is returned in the event of an error.
2 Job Variables To promote the task's error variable to a job variable, check the Store Output as Job Variable box. This copies the error value to a job variable. Job variables are similar to global variables; they are available to every task in the job.
3 Job Variable Names To set a custom name for the error variable, type the new name in the Job Variable Name field. Job Variable names must adhere to IAP Naming Conventions.

Masking Variables

Users can mask certain variables; masking will hide the result in Operations (Job) Manager when the workflow is run. If a variable is a reference variable, or a job variable, the factor that determines whether that variable is masked is by where the variable originated.

To enable masking, open the Task dialogue and toggle Mask to on.

06_Mask_2023_1

Masking JST Tasks

For JST tasks, you must mask all outgoing variables, or none of them (Figure 7).
