Conditional Branch

The Conditional Branch action A tool for building the processes, logic, and direction within workflows. directs your workflow along one of two paths, or branches depending on conditions you specify.

When the workflow runs, the Conditional Branch action chooses the Yes or No branch to use according to the conditions you set.

  • If the conditions are met, the workflow chooses the Yes branch.
  • If the conditions are not met, the workflow chooses the No branch.

You can only have two branches and you can set as many conditions as you want and the conditions can be as simple or as complex as you require.

When the action runs the conditions included in the expression are evaluated in order from the first to last condition and a TRUE or FALSE result is returned for the expression. You can use the AND and OR operators to combine two or more conditions.

Before you start 

Variables are placeholders that store information that changes each time the workflow runs or even during execution of a single workflow instance.

Each variable has a type that determines what values can be stored in the variable, such as a date, number, file path or a workflow user name. For example, if you want to save the name of an employee in a variable, you have to create a variable of type Text. The workflow can then store a name of the employee, such as "John," in the variable.

  • Text: Text string.
  • Boolean: Yes or No value.
  • Date/Time: Date and time value.
  • GUID: Globally unique identifier, often used to reference a list item in SharePoint.
  • Number: Integer number with decimal value.
  • Integer: Integer number with no decimal value.
  • Choice: A value that requests a selection from a list of allowed values.
  • Person or Group: A value that requests a selection from a user lookup.
  • Hyperlink: A value that requests a hyperlink URL and description.
  • Dictionary: A container that holds a single logical unit of variables. For more information, see Dictionary variables.
  • Collection: An index-based array of values, also known as an ordered list of values. For more information, see Collection variables.

In NintexOffice 365, the different categories of variables that can be used in a workflow are given below:

  • Start Variables: Workflow variables with the initiation option selected. Start Variables are used to get data from users when a workflow manually starts.

    • For more information on manually starting a workflow, see .

You can insert an existing Workflow Variable or Context Variable into the configuration fields of workflow actions A tool for building the processes, logic, and direction within workflows. and you can create user-defined variables for use throughout your workflow.

You can create user-defined variables from the Action configuration window when you are configuring a workflow action or from the toolbar of the designer page.

  1. In the Action configuration window, click in a field that accepts variables.
  2. Do one of the following depending on the method available;
    • On the drop-down list that appears, Click Create New Variable.
    • On the Insert Reference pane that appears, expand the Workflow Variables section and click Create New Variable.
  3. Do the following in the Workflow Variables pane to create the variable:
    1. For Name, type the variable name you want to use.
    2. Select a Type.
    • If you want to display the variable on the start form, select the Show on start form check box.
    1. Click Create.
  1. On the toolbar of the Designer page, click Variables. The Variables dialog box appears.
  2. Click New and fill in the following:
    1. For Name, type the variable name you want to use.
    2. For Type, select a variable type corresponding to the type of data you want to store.
    1. Click Save.

For more information, see User-defined variable types and Initiation options.

The following table describes the variable types available in the Variables dialog box as well as their initiation options, which are available when you select Yes for Initiation. Initiation options control the display and behavior of the variable on the start form that is displayed when a workflow is started manually.

    Workflow Variables Workflow variables configured for the workflow.

You can configure variables to collect data when a workflow is manually started. These variables will be shown on a start form used to initiate the workflow and allows users to specify a value for the workflow variable before the workflow starts, basically passing values into the workflow before it starts.

Variables displayed on a start form are also known as the "start data" of the workflow and represent data that must be collected when the workflow is started.

Note:  If the workflow starts automatically, then default values are used for start data.

To learn how to manually start a workflow, see Start a workflow manually.

Configure a variable to show on a workflow start form:

  1. Open the required workflow. The workflow designer opens.

  2. On the toolbar, click Variables. The Variables window opens.

  3. To edit an existing variable, click the required variable. The row becomes editable.

    or

    4. To create a variable, click New on the Variables window toolbar, enter a Name, and select the Type for the variable.

  4. Select the Initiation check box for the required variable.
  1. Click Save to commit changes.
