Hi,
We have multiple sales tax groups within our admin, some for only suppliers, some for only customers and some for both parties.
I want to get an error/pop-up when I try to post an invoice with a non-existing Tax Group.
For example, the Sales tax group is C-NL, and Item Sales Tax Groups SL does not exisit as combination C-NL-SL.
If I crreate a new free-text invoice and use Sales tax group C-NL, I don't want it possible at all to select Item Sales Tax Group SL
Or
I create a new free-text invoice and use Sales tax group C-NL, and Item sales tax group SL. And when I want to post the invoice, I want to get an error saying that it's not a valid combination so invoice can not be posted.
I did see this once while trying to post the exact same combination in our test environment, but its now gone.
Is this a possibily within D365? Is this an easy fix (switching a button on/off) or would this be a customization?
Many thanks for thinking along!
