how to add NetSuite native items/expenses sublist to custom records in NetSuite

AI generated answer (using internal Slack threads):

To add a NetSuite native items/expenses sublist to custom records in NetSuite, you can create a custom child record sublist. Here are the steps: 1. Create a custom record that will act as the child record. This record will contain the fields you want to display in the sublist. 2. In the custom record definition, there is a checkbox labeled 'Record is Parent'. Check this box. This will allow the custom record to act as a parent record and have child records associated with it. 3. Create a field on your child record that uses the list of the parent record. This will establish the relationship between the parent and child records. 4. On the parent record form, you can now add a sublist that references the child records. This sublist will display the fields from the child record and allow users to add and modify line items directly. Please note that the sublist will initially appear as view-only. To make it editable, you need to check the 'Allow Child Record Editing' checkbox in the sublist properties on the parent record form.
