a workflow that sets the shipping carrier and shipping method fields

AI generated answer (using internal Slack threads):

Based on the conversations, it seems that setting the "Shipping Carrier" and "Shipping Method" fields via a workflow in NetSuite can be a bit tricky. Here are some insights from the threads: 1. In a workflow, you can set the "Shipping Item" field, which corresponds to the "Shipping Method" in the Customer UI. When you set this field, NetSuite automatically sets both the "Shipping Method" and the "Shipping Carrier". 2. If you're unable to find the "Shipping Carrier" field in the workflow action to "set field value", it could be due to various reasons. One possibility is that the field is not available for workflows. Another possibility is that another workflow or script is affecting this field. 3. An alternative approach is to set the default shipping carrier on the customer page. This way, you wouldn't need to set it via a workflow. You should be able to mass update all the customers fairly quickly. 4. If you're trying to update the carrier information on an Item Fulfillment via scripting and running into issues, you might want to pay attention to the URL's query parameters when the page reloads. These parameters are usually default values that you can set. Here's a code snippet from the threads that shows how to set the carrier information:

javascript
switch (Number(stlToIfFields.custbody_shipping_company)) {
  case 1:
    // Fedex
    stlToIfFields.carrierform = 'fedex'
    stlToIfFields.shipcarrier = 'nonups'
  case 332:
    //Fedex Freight
    stlToIfFields.carrierform = 'fedex'
    stlToIfFields.shipcarrier = 'nonups'
  case 2:
    // UPS
    stlToIfFields.carrierform = 'ups'
    stlToIfFields.shipcarrier = 'ups'
  default:
    // Any other carriers
    stlToIfFields.carrierform = 'ns'
    stlToIfFields.shipcarrier = 'nonups'
}

log.debug(loggerTitle, `Record saved ID: ${stlToIfFields}`)

var updateIfShippingValues = record.submitFields({
  type: record.Type.ITEM_FULFILLMENT,
  id: ifID,
  values: stlToIfFields,
  options: {
    enableSourcing: false,
    ignoreMandatoryFields: true
  }
})
