Custom coding

AI Capabilities

The Custom Coding step in the Quality pipeline now supports AI-powered Natural Language Processing (NLP) capabilities. This allows users to describe logic in plain language, which the system automatically converts into equivalent JavaScript code.

Key Benefits

var id = input.get('ID'); 
  try { 
    // Explicitly convert to BigInt to handle integer input 
    var numId = BigInt(id); 
    // Check if ID is greater than 18 
    var isValid = numId > 18n; 
    // Set the output variable 
    output.set('IsValid', isValid); 
} catch (error) { 
    // Handle any conversion or processing errors 
    output.set('IsValid', false); 
} 

var fullName = input.get('FullName'); 
// Check if input is null or undefined 
if (fullName === null || fullName === undefined) { 
    output.set('FullName', null); 
} else { 
    // Trim whitespace and convert to lowercase 
    var processedFullName = fullName.trim().toLowerCase(); 
    // Set the processed fullname as output 
    output.set('FullName', processedFullName); 
} 

var inputDate = input.get('DateOfBirth'); 
try { 
    // Check if input date is null 
    if (inputDate === null) { 
        output.set('New_DoB', null); 
    } else { 
        // Use Java's DateTimeFormatter to format the date 
        var formattedDate = java.time.LocalDate.from(inputDate); 
        output.set('New_DoB', formattedDate); 
    } 
} catch (error) { 
    // Handle any formatting errors 
    output.set('New_DoB', null); 
} 

Setup Instructions

To configure AI capabilities for your workspace for custom coding operator ensure that you've enabled the feature via AI Manager, on detailed steps on how to configure it for your workspace refer to Features under AI documentation.

How to configure the custom coding step

Step Name: Defines the name for the step. Provide a meaningful name so that others editing the pipeline can easily identify its purpose.

Input Fields and Output Fields: The inputs and output field types are mapped to JavaScript types:

Example: Creating a user-defined isPrime() function to find prime numbers from an existing column.

function isPrime(num) {  
    // Handle numbers less than 2  
    if (num <= 1) {  
        return false;     
    }  
   // Check divisibility from 2 to the square root of num  
    for (let i = 2; i <= Math.sqrt(num); i++) {  
        if (num % i === 0) {  
            return false; // num is divisible by i, so it's not prime  
        }  
    }  
    return true; // num is prime  
    }  
output.set('IsPrime', isPrime(Number(input.get('CustomerId')))) 

try { 
    //script code 
    } catch (error) {   
    output.set(‘field’, -1); 
    } 

AI Assist: It is an NLP-based tool that helps you get started with AI capabilities in the Custom Coding step. It allows you to enter natural language instructions, which are then converted into JavaScript code snippets. Follow the steps given below to use AI Assist for the code:

Additional Features

• Data Preview: Use the data preview feature to validate that your script works as intended.
• Issues Tab: Syntax errors are highlighted in real time within the Monaco editor. If a script has errors but you still want to preview it, navigate to the Issues Tab to review and resolve the errors.

Best Practices

• Always test the script using the data preview functionality before finalizing.
• Ensure referenced fields are correctly declared to avoid validation errors.
• Use meaningful and consistent naming conventions for steps, input fields, and output fields.
