In Denmark the value of EU 3-party trade should be reported with the base amount. Although this is not possible.

On purchase document there is not a field to determ if this document is a EU 3-party trade

In the VAT statement it should be possible to have a filter if the amount contains both non 3-party trade and 3-party trade or just one of them.
