Need to write off transport costs


this is my first post. I hope this is the right section… ^^’

Here is my problem: I have booked an order as “Resources” and I inserted also tranport costs as “Charge”. I booked the delivery note. When I wanted to book also the invoice, I obviously found out that I could not assign the transport costs to the Resources voices…but I know from another past mistake that I can’t write off the transport costs.

How can I then solve this problem? Anyone can help? Thank you very much in advance,
