Just started working on this Sap Business one software. I am trying to generate an A/R invoice from delivery document. As soon as i tried to add an invoice i am getting this error "Tax account is missing" Our company doesn't charge tax to the customer. I have created a tax group for "EX" for 0% tax. There is a freight charges also on this invoice. I have done one more invoice without freight charges and it was fine. Can you help me on this?
