****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** To create a custom suitelet that selects lots and automatically fills and closes the inventory detail popup, you would need to use SuiteScript. However, it's important to note that SuiteScript has limited support for subrecords in client scripts, and essentially no support for sublists on the subrecord. You can't set inventory details in a beforeLoad entry point, and as you've discovered, you can't set sublists on the subrecord in client script. The closest you will get via SuiteScript is a client script deployed on the inventory detail record. You also can't use dynamic mode methods like

selectLine

when working with records in standard mode. Instead, you should use methods that have a line parameter, like

Record.getSublistSubrecord

. Your alternatives are varying levels of DOM manipulation. However, this approach is not officially supported by NetSuite and may lead to issues in the future if NetSuite changes their DOM structure. In conclusion, while it's technically possible to create a custom suitelet that selects lots and automatically fills and closes the inventory detail popup, it would require a significant amount of custom scripting and may not be fully supported by SuiteScript.
