How to Auto-Select Lot Information on NetSuite Sales Orders?

Automatic lot selection for sales orders must be implemented within a 'before submit' user event script. This timing is critical because NetSuite prevents saving a sales order if a lot-numbered item has a lot number specified but no lot assigned. Implementing the logic in a 'before submit' script ensures that lot information is correctly assigned or validated prior to the record being saved.A key consideration for this automation is the availability of item receipts for the specific customer and item. The script would need to identify and select available lots based on predefined criteria.This functionality can be achieved through scripting. When working with Inventory Detail, it is necessary to interact with subrecords using SuiteScript 2.x APIs, such as N/record module's getSubrecord() or N/record module's getSublistSubrecord(). If the requirement is not to manipulate the Inventory Detail subrecord directly but rather to access the lot number at the line level, the lot number column can be accessed directly.
