Custom Job Steps Skill

This skill guides you through creating new custom job steps for Salesforce B2C Commerce batch processing.

Running an existing job? If you need to execute jobs or import site archives via CLI, use the b2c-cli:b2c-job skill instead.

When to Use

• Creating a new scheduled job for batch processing
• Building a data import job (customers, products, orders)
• Building a data export job (reports, feeds, sync)
• Implementing data sync between systems
• Creating cleanup or maintenance tasks

Overview

Custom job steps allow you to execute custom business logic as part of B2C Commerce jobs. There are two execution models:

File Structure

my_cartridge/
├── cartridge/
│   ├── scripts/
│   │   └── steps/
│   │       ├── myTaskStep.js       # Task-oriented script
│   │       └── myChunkStep.js      # Chunk-oriented script

└── steptypes.json                  # Step type definitions (at cartridge ROOT)

Important: The steptypes.json file must be placed in the root folder of the cartridge, not inside the cartridge/ directory. Only one steptypes.json file per cartridge.

Task-Oriented Steps

Use for single operations like FTP transfers, file generation, or import/export.

Script (scripts/steps/myTaskStep.js)

'use strict';

var Status = require('dw/system/Status');
var Logger = require('dw/system/Logger');

/**
 * Execute the task step
 * @param {Object} parameters - Job step parameters
 * @param {dw.job.JobStepExecution} stepExecution - Step execution context
 * @returns {dw.system.Status} Execution status
 */
exports.execute = function (parameters, stepExecution) {
    var log = Logger.getLogger('job', 'MyTaskStep');

    try {
        var inputFile = parameters.InputFile;
        var enabled = parameters.Enabled;

        if (!enabled) {
            log.info('Step disabled, skipping');
            return new Status(Status.OK, 'SKIP', 'Step disabled');
        }

        // Your business logic here
        log.info('Processing file: ' + inputFile);

        // Return success
        return new Status(Status.OK);

    } catch (e) {
        log.error('Step failed: ' + e.message);
        return new Status(Status.ERROR, 'ERROR', e.message);
    }
};

Status Codes

// Success
return new Status(Status.OK);
return new Status(Status.OK, 'CUSTOM_CODE', 'Custom message');

// Error
return new Status(Status.ERROR);
return new Status(Status.ERROR, null, 'Error message');

Important: Custom status codes work only with OK status. If you use a custom code with ERROR status, it is replaced with ERROR. Custom status codes cannot contain commas, wildcards, leading/trailing whitespace, or exceed 100 characters.

Chunk-Oriented Steps

Use for bulk processing of countable data (products, orders, customers).

Important: You cannot define custom exit status for chunk-oriented steps. Chunk modules always finish with either OK or ERROR.

Required Functions

Optional Functions

Script (scripts/steps/myChunkStep.js)

'use strict';

var ProductMgr = require('dw/catalog/ProductMgr');
var Transaction = require('dw/system/Transaction');
var Logger = require('dw/system/Logger');
var File = require('dw/io/File');

    fileWriter.writeLine('ID,Name,Price');

    // Query products
    products = ProductMgr.queryAllSiteProducts();
};

/**
 * Get total count for progress tracking
 */
exports.getTotalCount = function (parameters, stepExecution) {
    return products.count;
};

/**
 * Read next item
 * Return nothing to signal end of data
 */
exports.read = function (parameters, stepExecution) {
    if (products.hasNext()) {
        return products.next();
    }
    // Return nothing = end of data
};

/**
 * Process single item
 * Return nothing to filter out item
 */
exports.process = function (product, parameters, stepExecution) {
    // Filter: skip offline products
    if (!product.online) {
        return;  // Filtered out
    }

    // Transform
    return {
        id: product.ID,
        name: product.name,
        price: product.priceModel.price.value
    };
};

/**
 * Write chunk of processed items
 */
exports.write = function (items, parameters, stepExecution) {
    for (var i = 0; i < items.size(); i++) {
        var item = items.get(i);
        fileWriter.writeLine(item.id + ',' + item.name + ',' + item.price);
    }
};

/**
 * Cleanup after all chunks
 */
exports.afterStep = function (success, parameters, stepExecution) {
    // Close resources
    if (fileWriter) {
        fileWriter.close();
    }
    if (products) {
        products.close();
    }

    if (success) {
        log.info('Chunk processing completed successfully');
    } else {
        log.error('Chunk processing failed');
    }
};

Parameter Types

Parameter Validation Attributes

Configuration Options

steptypes.json Attributes

Context Constraints: @supports-site-context and @supports-organization-context cannot both be true or both be false - one must be true and the other false.

Best Practices

1. Use chunk-oriented for bulk data - better progress tracking and resumability
2. Close resources in afterStep() - queries, files, connections
3. Set explicit timeouts - default may be too short
4. Log progress - helps debugging
5. Handle errors gracefully - return proper Status objects
6. Don't rely on transactional=true - use Transaction.wrap() for control
