Understanding the Problem

The provided SSJS script is designed to update mobile phone numbers in a data view. However, the script uses a string literal “NewMobileNumber” instead of the variable newMobileNumber, which contains the actual new mobile number.

Root Cause

The root cause of the issue is the incorrect use of a string literal instead of a variable reference in the update script. This prevents the script from updating the mobile phone numbers correctly.

Fixing the Issue

To fix the issue, the script needs to be updated to use the correct variable reference. The corrected script should look like this:

updated_ssjs_script.js

var mobileAddressDataView = DataExtension.Init('_MobileAddress');
var batchDataExtension = DataExtension.Init("MobileConnectPhone_Updated");
var data = batchDataExtension.Rows.Retrieve();
for (var i = 0; i < data.length; i++) {
    var contactId = data[i].ContactID; 
    var newMobileNumber = data[i].NewMobileNumber;
    var result = mobileAddressDataView.Rows.Update({_MobileNumber: newMobileNumber}, ['_ContactID'], [contactId]);
}

The key change is replacing the string "NewMobileNumber" with the variable newMobileNumber in the update script.

Best Practices

To avoid similar issues in the future, it is essential to follow best practices when writing SSJS scripts. This includes using correct variable references and testing scripts thoroughly before deploying them to production.

Heads up: Always test your scripts in a sandbox environment before deploying them to production to avoid any unintended consequences.

Checklist

• Test scripts in a sandbox environment
• Verify variable references are correct
• Check for any syntax errors
• Test scripts with sample data
• Deploy scripts to production only after thorough testing
