I have installed the Lot Auto Numbering SuiteApp. When I check the Inventory Detail sublist on the item record, the inventory numbers are not showing under the tab. However, in the Customize Form settings, the "Inventory Numbers" sublist is enabled and visible.

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** Based on the conversations, it seems that the issue you're facing is related to the visibility of custom fields in the Inventory Detail sublist after installing the Lot Auto Numbering SuiteApp. From the discussions, it's clear that the Lot Auto Numbering SuiteApp does not create any custom fields for the inventory details record. Instead, it allows you to create a lot number sequence on the item record and include additional lot number fields as part of the lot number that is generated by the SuiteApp. It's also important to note that it's not possible to add custom fields to the inventory details pop-up. This could be why you're not seeing the inventory numbers under the Inventory Detail tab, even though the "Inventory Numbers" sublist is enabled and visible in the Customize Form settings. Regarding the customization of the Inventory Assignment sublist, it appears that this is not an option via SuiteScript for native fields. The closest you can get is to add your own field with options you add yourself and use that field to set the native field. Please review the documentation for

Field.insertSelectOption

and

Field.removeSelectOption

to understand the restrictions related to select options. These methods might help you to filter and customize the results in the dropdown that shows Lot number/Serial Numbers based on certain criteria.
