How to show a pop-up with customer exceeding credit limit on sales order

AI generated answer (using internal Slack threads):

To show a pop-up with a customer exceeding the credit limit on a sales order, you can use a Client Script in NetSuite. This script will be triggered when a field changes, in this case, the item field on the sales order. Here is an example of how you can do this:

javascript
function fieldChanged(context) {
    // Check that the field that changed was the item.
    if(context.sublistId == 'item' && context.fieldId == 'item') {
        // Retrieve the Customer.
        var customer = context.currentRecord.getValue({fieldId: 'entity'});
        
        // Retrieve the customer's credit limit.
        var creditLimit = search.lookupFields({
            type: search.Type.CUSTOMER,
            id: customer,
            columns: ['creditlimit']
        }).creditlimit;
        
        // Retrieve the customer's balance.
        var balance = search.lookupFields({
            type: search.Type.CUSTOMER,
            id: customer,
            columns: ['balance']
        }).balance;
        
        // Check if the balance exceeds the credit limit.
        if(balance > creditLimit) {
            // Show a popup.
            alert('Customer balance of ' + balance + ' exceeds the credit limit ' + creditLimit);
        }
    }
}

This script will retrieve the customer's credit limit and balance when an item is added to the sales order. If the balance exceeds the credit limit, a pop-up will be shown with a message indicating this. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
