Hi all,
Working in NAV 2016, our company has been trying to set up prepayment requirements for certain customers to avoid our warehouse accidentally shipping items before prepayment has been made (previously it was monitored manually - finance informing warehouse when payment was made, then warehouse shipped)
We tried this out in a test version of our system, and it would not cooperate properly because it made an error when trying to ship+invoice an order that had been prepaid, where payment had been allocated to the proforma invoice. We decided that didn't matter and just wanted at least make it so the warehouse wasn't able to ship+invoice until I (as the one who posts customer payments) went to the order and put a 0% in the prepayment requirement. So still a bit of unnecessary manual work but it's very few prepayments we receive anyway
But! Now the sales team made a new order with a prepayment on it and wanted to send the order confirmation/proforma invoice to the customer the way they have always done, and suddenly there's a "prepayment specification" on the order confirmation and it has added a 20% VAT charge when the order is without VAT. I cannot figure out how to change this? Hope someone can help! See this screenshot where I can see it's trying to add the VAT charge:

Hoping someone can help on how to remove this VAT charge, and without having to post the proforma invoice itself (as we cannot get this to work due to other errors, and because it would create extra unnecessary work for the sales team, and we are planning to change to BC within the next few months anyway)
