A task is a request for a human to perform an action. In process modeling, you use tasks to assign them to the human activities in your process. Human activity is a type of flow object in the process you model that illustrates an activity that a human performs.

After you create the task, you can edit the task to define its attributes.

When working with tasks, you can do the following:

  • Create the task.

  • Assign a User Interface (UI) to the task.

  • Define task owners.

  • Define task administrators.

  • Define time constraints for the task.

  • Define task priorities.

  • Define a name and description of the task.

  • Define user texts for the task.

Prerequisites

You have opened the Process Composer perspective in the SAP NetWeaverDeveloper Studio and have expanded your project in the Project Explorer view.

Procedure

Creating the Task

  1. Expand Process Modeling.

  2. In the context menu of the Tasks folder, choose New....

  3. In the dialog that appears, specify a name of the task in the Name field.

  4. (Optional) Specify a description in the Documentation field and choose the Finish pushbutton.

Assigning a User Interface to the Task

For more information, see Assigning a User Interface to a Task.

Defining Task Owners

You can define owners of the tasks that you assign to human activities in your process model. You define task owners on one of the following levels:

  • Lane level

  • Human activity level

  • Task level

For more information, see Defining Task Owners.

Defining Task Administrators

For more information, see Defining Task Administrators.

(Optional) Defining Time Constraints

The time constraints are deadlines that refer to the activation, start, completion and expiration time of the task. For more information about defining time constraints, see Defining Time Constraints of a Task.

(Optional) Defining Task Priorities

  1. Expand Process Modeling, then expand Tasks.

  2. In the context menu of a task, choose Open.

    The task editor opens.

  3. Select a priority from the dropdown menu under Priority on the Overview tab page.

(Optional) Defining Name and Description of the Task

You specify a name of the task when you create the task. In the task editor you have the option to rename the task.

  1. Expand Process Modeling, then expand Tasks.

  2. In the context menu of a task, choose Open.

    The task editor opens.

  3. Choose the Rename... pushbutton under General Information on the Overview tab page.

  4. In the dialog that appears, specify a new name of the task in the New Name field and choose the Finish pushbutton.

  5. (Optional) Specify a description of the task in the Documentation field.

(Optional) Defining User Texts

User texts are the subject and the description of a task that the processor of the task sees. You can parameterize user texts to provide them with dynamic content. You use variables to parameterize user texts.

  1. Expand Process Modeling, then expand Tasks.

  2. In the context menu of a task, choose Open.

    The task editor opens.

  3. Choose the Add pushbutton under Variables on the User Texts tab page to add a variable.

    The system automatically fills in values in the Name and Type fields, which you can edit. You define an expression with the expression editor.

  4. Select the value in the Name field to rename the variable.

    Caution Caution

    You can only use the letters A–Z, the numerals 0–9 and an underscore (_) in the variable name.

    End of the caution.

  5. Select a type of the variable from the Type dropdown menu if you want to change the type that was filled in by the system.

    You must set a type before you create an expression.

  6. Choose the Edit... pushbutton to define an expression in the Expression Editor. Choose the OK pushbutton.

    For more information about expressions, see Creating Expressions.

    Caution Caution

    The return value of the expression you create must match the type you select in the Type field of the Variables table.

    End of the caution.

  7. Specify a subject of the task in the Subject field and a description in the Description field under Parameterized Texts.

    Use braces ({}) to reference the variables you defined under Variables. You reference a variable by putting the variable's name between the braces.
