Retroactive corrections made

Dear Roosje,

If you have made adjustments to your quarters, you will need to submit a new vAT declaration for all of these quarters. Otherwise, your returns will no longer be correct and you will encounter issues with the tax authorities. Best regards and good luck from Gitta :-)

How do I make it okay? My apparently not-so-logical brain assumed that if I open the quarters back, make the necessary updates, and close the quarters again, this would be picked up in the next quarterly return. So I misjudged the situation :-)

How can I best do this in Dexxter?
