This is my setup for a specific item group/item model group:
Upon sales order invoicing, this is what the voucher looks like.
But some of the sales order vouchers (items using the same item group/item model group), looks like this.
What should we do, all the sales order vouchers should look like the 2nd picture with 2 lines only. Since this is a revenue from sales orders.
What setup should we remove? And why does it apply only to few invoices?
PS: Both invoices/vouchers did NOT go through packing slip.
