can i prevent duplication of item names?

AI generated answer (using internal Slack threads):

Yes, you can prevent duplication of item names in NetSuite. There are a couple of ways to achieve this: 1. User Event Script: You can write a User Event (UE) script that runs on the beforeSubmit event. This script would perform a search or query on items to ensure that your item's custom field (e.g., 'custitem_no') does not already exist. If it does, the script would throw an error, preventing the item from being saved. However, this method might not work with concurrent saves. 2. Custom Record with External ID: If you need to handle concurrent saves, you could create a custom record with an external ID set to the 'custitem_no'. You can rely on the external ID to guarantee uniqueness. This method would require logic to find the original custom record and edit it if the 'custitem_no' changes. 3. Client Script: If you want to check for duplicate item names as soon as the user enters an item name and moves to the next field (instead of clicking the Save button), you can use a client script. This script would run a search as soon as the user tabs out of the Item Name/Number field, and display a warning message if a duplicate item name is found. Remember, these methods require some knowledge of SuiteScript, NetSuite's JavaScript-based API. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
