- Basic Activities
  - Activities Used to Create Workflows
    Activities comprise the main building blocks or steps that perform the actions in a subprocess or workflow.
  - Third-party Activities
    Workflow can utilize third-party activities that are compatible with Microsoft Windows Workflow Foundation.
  - Predefined User Activities
    A user activity defines part of a user-defined process in a workflow process step. For a workflow to run, all user activities must be valid (contain no errors) and enabled (active).
  - Data Access Activities
    These activities are used for passing information and data between workflows and activities.
    - Call Method Activity
      The Call Method activity allows you to use a call method from a service provider to access information in other areas of the application.
      - Configure the Call Method activity
    - Call Web Method Activity
      The Call Web Method activity allows you to call an external web service method that contains parameters defined as part of the workflow.
    - Code Activity
      The Code activity allows you to write custom logic; therefore, you can augment the functionality of a workflow to meet your needs.
    - Index Activity
      An Index activity is used with any collection of data to look up a value at a specified index on the collection.
    - Read Data Items Activity
      The Read Data Items activity allows a subprocess to access data items outside of the workflow. This activity reads data from the data items defined at the workflow or subprocess level to make them available to other activities.
    - Write Activity
      The Write activity performs a set of writes to workflow variables. The source of each write can be an expression, a bind, or a user-defined absolute value.
    - Write Data Items Activity
      The Write Data Items activity allows a subprocess or step to access data items outside of the workflow. The Write Data Items activity writes data to data items at the workflow or subprocess level.
  - Workflow Control Activities
    These activities are used for creating changes in a workflow, such as starting or stopping activities, during run time.
  - Message Queue Activities
    These activities are used for working with a messaging queue in order to co-ordinate work between workflows and activities.
  - Flow Control Activities
    These activities are used to create multiple execution layers within workflow logic.
  - Event-based Activities
    These activities are used when you require workflow logic to start an event during run time.
  - Keyword Activities
    You can use keywords to replace text in work instructions and email subjects and bodies. This text is replaced with keyword values in a workflow at run time.
  - Operator Activities
    These activities are used by operators when a workflow is running the Task List.
  - eSOP Activities
    These activities are used when working with the eSOP Editor.

Best Practices

Call Method Activity

The Call Method activity allows you to use a call method from a service provider to access information in other areas of the application.

The outputs of the call method are available as variables to the rest of the workflow. For example, you can call a method in the production model to get the current status of a work request.

Input and Output Parameters

After selecting a call method from the Configure Method dialog box, configure the input and output parameters. You can bind workflow level variables to the inputs. Output parameters can be bound to local variables or output parameters of parent activities, and the values will be written to those variables when the method executes.

Enforce User Permissions

You can invoke a security check when service provider method calls are made within a workflow.When configuring a Call Method activity, go to the Security area to ensure that, at run time, the current user who has acquired the task step has permission to call the method.

Note: For this feature to function correctly, you must configure a subprocess in one of the following ways to ensure that a user acquires the task step. Then, to verify that the task step is acquired, check the Current User property on the subprocess to ensure it is not null.

Manual Start is set to True.
A Form activity is used before the method call.
