in make case I am using in this way:
I have CSV file to do by cron function and every day they update NAV and the date, product and share class are relationship and they have been created before, so only I need to pass the id of them: and it works fine.
maybe is not what you are looking for. :slight_smile:

const newItem = await strapi.entityService.create('api::nav.nav', {
          data: {
            nav: itemFromCSVFile.nav,
            date: itemFromCSVFile.date,
            product: itemFromCSVFile.product,
            share_class: itemFromCSVFile.share_class
          },
        })
      });
