Decision Operator

Overview

The Decision operator lets you build simple logic statements that evaluate whether input values meet specific conditions. Based on the result, the operator outputs true or false, letting you control the flow in a  Data Workflow.

To configure a Decision operator, use the Info window and define a condition. This condition uses comparison symbols, like <, >, =, >=, or <=, to evaluate incoming data. For example, to check if an end-user's End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product. income is greater than 100,000, your condition might look like the following: A > 100000. Here, A represents the incoming value, and 100000 is the threshold.

For more advanced logic, you can use an OR statement. For example, OR(A="a", A="b", A="c"). This configuration returns true if the input value matches "a", "b", or "c". All other values return false.

The Decision operator evaluates conditions and routes data based on the result. It passes data through one output port at a time. The port that does not receive data displays as _BLOCKED, and any steps connected to that port will not execute.

Using Arguments in Conditions

You can configure a Decision operator to evaluate a condition using an argument from another operator.

For example, you'll:

• Connect another operator to the argument port (top) of the Decision operator.

• Enter _arg in the Condition field.

The argument must return a string A string is an object that represents a sequence of characters. Strings typically hold data represented in text form. or Boolean The Boolean data type accepts one of two values: true, or, false. value. Your condition should use a standard comparison format, like <, >, =, >=, or <=. The condition must be either TRUE or FALSE.

You'll find the Decisions operator under the Gateways group to the left of the Data Workflow canvas.

About the Info Window

Learn more about each setting in the Decision operator's Info window:

Setting	Description
Category	Grayed out and non-adjustable setting indicating the operation type.
Input List	Select the Property ID for the data you want your Decision operator to process. This selection should match the Property ID you've selected in your Input operator. This field is optional, but making a selection displays a label below your operator. These labels can help to keep your canvas organized.
Preserve Argument Type	When selected, this setting ensures the argument data type is respected when the operator executes.
Condition	Here, you'll set the expression the operator runs your data against. You'll use <, >, =, >=, or <= to set your expression. You can also use a combination of these, set inside an OR statement. For example, OR(A="a",A="b",A="c"). To use another operator as an argument, connect the operator to the argument port and enter _arg.

Adding a Decision Operator

To see how the Decision operator works, you’ll walk through a simple example. In this example, you’ll create a module that collects an end-user’s income. Then, you’ll use a Data Workflow to recommend a financial adviser to the end-user End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product. based on the income entered.
