Hello team! I am importing data for a custom record on NetSuite but I'm having a lot of import errors that I can't really figure out. Among other things, this screenshot shows some recurring errors that block the import. In addition, with regard to the serialized boxes, I made sure to have adjusted the stock before proceeding with the import.

if its about item reference, then you have to use Item name and Display name, so two fields separated by space. So it would much easier if you assign to the item an external id and then use external id instead of the name.

Thanks @Arūnas Žindžius
