Can you link already existing inventory items to a matrix item as a child product

AI generated answer (using internal Slack threads):

Based on the conversations provided, it seems that you cannot directly link already existing inventory items to a matrix item as a child product. Matrix items in NetSuite are typically used to represent a parent-child relationship between items, where the parent is a non-sellable item and the children are the sellable variants of the parent. However, if you're trying to group items together, you might want to consider using a Kit item. A Kit item in NetSuite is a type of item that is a collection of other items. When a Kit item is sold, all the components of the kit are also sold. If you're trying to convert Matrix Inventory Items into Lot Numbered Items, it seems there isn't an easy way to convert most item types into other item types. You might need to create new lot numbered items that mirror your old Inventory Items. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
