VAT Rate Change Tool in Microsoft Dynamics NAV 2013: The Microsoft Dynamics NAV team offers some info on this tool here.
Dynamics NAV helps streamline routine accounting practices with automated financial processes, according to the author of the post, Nuno Bento, a program manager at Microsoft.
Bento says in Dynamics NAV, you can set up multiple VAT rates using the VAT posting groups and general posting groups so that you can easily change VAT rates in order to maintain accurate VAT reporting. But companies often have thousands of open documents or journal lines where it would be time-consuming to manually update the VAT posting groups and general posting groups.
