This has been recorded as a bug, which Microsoft will fix, but I have been asked by Microsoft to also create an idea (don't know why).

For several of our customers, sale of scrap is posted by a supplier credit note (and not a sales invoice), which will create a VAT transaction with a direction "Tax free purchase". The result for box C is a "minus" amount instead of a "plus" amount, which is wrong. The same box consist of sales invoices, which has VAT transactions with "Tax free sales". So the ER report for box C is taking Tax free purchase with the wrong sign. A correction is needed, so VAT transactions with direction "purchase" is added with inverted sign (of what it has today) .

It is not possible for these customers to use the DK VAT declaration directly to be reported to the Danish tax authorities, before this issue has been solved.

According to the new Danish bookkeeping act, the system (D365) should be able to do an automatic reporting to the authorities.
