**Figure 1: Business Logic**

### Start

(See **Figure 2**)

The Start building block enables you to specify the starting point (s) of your digital process. It contains the following fields and options:

- Source (required):
  - Salesforce
  - MS Dynamics
  - Direct Link
  - Journey Sender
  - API
- Unique Identifier
- Description

**Figure 2: Start and More Options**

NOTEAfter creating a new process and accessing the Workflow Manager for the first time, it appears with a default Starts building block - Any. The Any Start building block is the default entry point for handling initiations from a source not explicitly defined in the workflow.

### Condition

(See **Figure 4**)

The Condition building block allows you to create and configure conditions that split the path of your process into different directions and scenarios. It contains the following fields and options:

- Add Label
- Edit Logic
- Description

![](https://cdn.document360.io/45e1a1b1-1964-46f1-939e-f40bde9b50fa/Images/Documentation/image-1736456130005.png)

**Figure 4: Condition**

#### Edit Logic

(See **Figure 5** and **Figure 6**)

Clicking the Edit Logic button displays the Edit Logic window. In this window, you can create logical expressions that split and determine the path of the digital process.

**Figure 5: Edit Logic Window**

To create a logical expression, select if it will be triggered when its result is True or False. Then add the first condition and set its parameters:

- Selector - a data item or metadata item
- Comparison Operators:
  - Equal to
  - Is not
  - Greater than
  - Less than
  - Is Empty
  - Is Not Empty
- Value:
  - Textual or numeric
  - True or False in case the added Selector is a boolean-type data item

A logical expression can include more than one condition. After clicking the + Add Condition button, another condition row appears.

**Figure 6: Logic with Multiple Conditions**

NOTE

When adding more than one condition, it is mandatory to set the operation between them: And/Or.

### Model Update

(See **Figure 7**)

The Model update allows you to define a value directly in the data/metadata items from the workflow canvas. It contains the following fields and options:

- Add Label
- Set Model Data
- Description

![](https://cdn.document360.io/45e1a1b1-1964-46f1-939e-f40bde9b50fa/Images/Documentation/image-1757079258286.png)

**Figure 7: Model Update**

#### Set Model Data

(See **Figure 8** and **Figure 9**)

Clicking the Set Model Data button displays the Write Data to Model window. In this window, you can add selectors (data/metadata items) and set their values.

**Figure 8: Write Data to Model**

To add the first data/metadata item, click the Add selector field and select a data item, then add its value, for example:

Click + Add Field to add additional rows.

### End

(See **Figure 10**)

The End building block allows you to indicate when the process or one of its paths has ended. It contains the following fields and options:

- Add Label
- Description
