We want to push this data from Salesforce to Netsuite to create a Sales Order. The use case is that we have an Item Group inside Salesforce and the users inside Salesforce provide quantities and other custom data to the line items inside the item group. But I am struggling to get the details across at a line item level. Currently I able to supply the Item Group and see then look in Netsuite and see the items automatically added to that item Group. But when I try to update the values of the items in that item group I seem to great new items outside the item group. Is it possible to insert a Sales Order with an item group and the items inside that group via the Netsuite API?
