Fixing RCRD_HAS_BEEN_CHANGED on NetSuite Work Orders

  ## Why RCRD_HAS_BEEN_CHANGED Happens

  NetSuite throws the `RCRD_HAS_BEEN_CHANGED` error when a record changes between the time it is loaded and saved.

  ## Common Causes

  - Multiple scripts updating the same Work Order
  - A workflow running during the save
  - Two Map/Reduce executions processing the same record
  - A user editing the Work Order while a script is running

  ## Example

  ```javascript
  const workOrder = record.load({
    type: record.Type.WORK_ORDER,
    id: workOrderId,
  });

  workOrder.setValue({
    fieldId: "memo",
    value: "Updated by script",
  });

  workOrder.save();
  ```

  ## Best Practice

  Use `record.submitFields()` when you only need to update body fields.

  ```javascript
  record.submitFields({
    type: record.Type.WORK_ORDER,
    id: workOrderId,
    values: {
      memo: "Updated safely",
    },
  });
  ```
