Hello Everyone, I created a custom record type which is appearing as a sbulist on item form now when uploading an item i am unable to see the fields of that custom record type is there any way to have those fields in csv import ?

Yes but you need to select custom record instead of item as your import type

@MGBC is correct, custom record is not a part of item record so you wont be able to import it with the items, has to be done separately, How is your sublist is referenced? Is the custom record is a child record of the item?

Yes the custom record is a child of item record and you guys are correct that we can't import with items. Thank you so much for the help!
