- 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.
    - 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.
      - Configure an Index activity
      - Index a directory resource against a global subprocess to be used during run time
    - 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.

Index Activity

An Index activity is used with any collection of data to look up a value at a specified index on the collection.

An Index activity allows you to select a single row or column out of a DataTable data type. Historian is a common source of data tables that can be accessed through Data Items. To access a cell of a data table, insert two Index activities. The first Index activity selects the row, and the second binds to the output of the first Index activity to select the column of that row.

Properties

The Index activity contains the following configuration options:

Property	Value	Description
Collection	System-defined	Use the drop-down arrow to bind a compatible resource property from an activity, the containing subprocess, a global subprocess, or a workflow. Click the ellipsis button to change these settings.
Index Type	System-defined	Allows you to choose the appropriate data type for the resource in the column or row to be selected. The available data types depend on the variable that you select in the Collection field.
Index	System-defined	Allows you to select a row, bind to another resource, or to create an expression based on the value.
Outputs	Result; System-defined	Displays the output value of the Index activity. Note: If sufficient metadata is available, when indexing the rows collection of the DataTable, there is an output property for each column in the table.
