how to filter list of items in Purchase order based on brand in PO against custom field in item master

AI generated answer (using internal Slack threads):

To filter the list of items in a Purchase Order (PO) based on a brand or any other custom field in the item master, you would need to use SuiteScript to create a custom field and then use a client script to dynamically add the select options. Here's a high-level overview of how you can achieve this: 1. Create a custom field in the PO that corresponds to the brand or category you want to filter by. This can be done using the beforeLoad event in a User Event Script. 2. Create a client script that will populate the item dropdown based on the value selected in the custom field. This script should be triggered on field change of the custom field. 3. In the client script, you can use a search to get the list of items that match the selected brand or category. You can then use this list to populate the item dropdown. Please note that this solution requires knowledge of SuiteScript and NetSuite's scripting API. If you're not comfortable with scripting, you might want to consider hiring a NetSuite developer or partner to help with 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. ******
