Tax exempt number not specified

Hi, I get the error Tax exempt number not specified when posting the Free text invoice, but I’ve set the Tax exempt number requirement to none in the AR parameters. Is there anywhere else to change the setup?

Hello, I believe you got this error starting with version 10.0.41, true?
Because in that version it seems that the tax registration number logic has changed, to support invoice lines having different tax registration numbers. But the AR parameter to turn the control off (see image attached), is not visible/available unless a whole lot of more advanced tax logic is setup. This is now a blocker for my client to upgrade to 10.0.41 in their production environment.
