Sales Order Agent Permissions Error
Look to see if you have a custom Permission Set that gives read access to the TableData 27014501 NWV VAT Invoice Setup.
If you can't find one, you may need to create a new custom Permission Set and add the read access to that TableData.
Add this custom Permission Set to the user.
You may get a different error after this for another missing permission/TableData. If so then add that too to your new custom permission set. And keep going like this until it works for that user.
