Warning message : The vendor you have selected is based in a nexus for which you are required to charge a different kind of tax.

The user wants to change the Vendor for a Purchase Transaction, but receives the error: The vendor you have selected is based in a nexus for which you are required to charge a different kind of tax. Click OK to change the form to one that is applicable for that Nexus.

The reason for the warning message is because the default shipping address of the Vendor, in particular the country information, is not a supported Nexus of the Subsidiary. To resolve, the user may check the supported Nexuses of the Subsidiary by doing as follows:

1. Navigate to Setup > Company > Subsidiaries

2. Click View on the Subsidiary 

3. Click on Nexuses tab

Note: In cases wherein the user cannot save the Purchase Order, the alternate solution is to set the default shipping address of the Vendor to the country supported by the Subsidiary or use the same country as the old vendor. The user may also verify if the currency used by the new Vendor is the same as the old Vendor to avoid any error.
