You see the error "Tax override cannot be applied. Nexus is not configured for XX" in your Error file from a transaction import.
- You need to add nexus:
- If you do not have nexus activated for the state you cannot do an import that has a tax override
- Check that the state is selected AND that the transaction is dated during the active time (between the start and end dates)
- Go to Organization > click Nexus > go to the State and check that it is selected, verify dates
