Logic At Most Component

Use the Logic At Most component to check that no more than a specified maximum number of inputs are true. This component is useful for setting upper limits and ensuring that a certain threshold is not exceeded.

Why this matters

Many processes require upper bounds or limits. The Logic At Most component is perfect for enforcing these rules, such as "trigger an alert only if at most 2 out of 10 services are offline" or "approve a request automatically if at most 1 flag is raised." It allows you to create workflows that can handle acceptable failure rates or tolerance levels gracefully.

Step 1: Set the Maximum Limit

This is the core setting of the component. You define the maximum number of inputs that can be true for the "Verified" path to be taken.

Setting	Description
Maximum Inputs	Define the maximum number of inputs (from 0 to 9) that can have a true value to trigger the Verified output.

How Inputs are Evaluated

• True: Any input that has a value (e.g., a non-empty string, any number, the boolean true, an object, an array).
• False: Any input that is empty, null, undefined, or the boolean false.

Step 2: Provide Inputs

You can add multiple inputs to the component, each representing a condition to be checked against the maximum limit.

Action	Description
Add Input	Click the + icon to add a new input field. Give it a descriptive name that reflects the condition you are checking.

Step 3: Handle the Outputs

The component has two output branches, allowing you to direct the workflow based on whether the maximum limit was respected.

Output	Description
Verified	This path executes if the number of true inputs is less than or equal to the specified maximum.
Unverified	This path executes if the number of true inputs is greater than the specified maximum.

Branching Your Workflow

Connect the Verified output to the steps that should run when the condition is met (i.e., the limit was not exceeded). Connect the Unverified output to a path that handles the "too many" case, such as escalating to a human or logging a critical error.

Best Practices

• Enforce Business Rules: Use this component to enforce rules like "a user can have at most 3 active sessions" or "a discount code can be applied to at most 1 promotional item."
• Check for Low Error Rates: In a quality control workflow, you could run several checks and use Logic At Most to pass an item if it has, for example, at most 2 minor defects.
• Gatekeeping and Escalation: Use this to automatically handle simple cases while escalating more complex ones. For example, "if at most 1 issue is detected, proceed; otherwise, create a support ticket."
• Set Maximum to 0 for a NOR Gate: If you set Maximum Inputs to 0, this component behaves like a logical NOR gate, meaning the Verified path only runs if all inputs are false.

Troubleshooting Tips

If your logic isn't branching as expected...

• Check the Maximum Setting: Ensure the Maximum Inputs value is set correctly for your use case.
• Inspect Your Inputs: Use the Debug panel to check the actual values being passed to each input. An input you believe is false might have an unexpected value (like the string "false"), causing it to be evaluated as true.
• Verified vs. Unverified Path: Double-check that you have connected your downstream components to the correct output path (Verified or Unverified) based on your intended logic.

What to Try Next

• Use this component after a ForEach Loop to check that at most a certain number of items in the list failed processing.
• In a fraud detection system, check several risk indicators and use Logic At Most to allow a transaction if it triggers at most one low-level warning.
• Combine this with Logic At Least to check for a range, for example, "Verified if at least 2 AND at most 4 conditions are true."
