6. You can see the following process communication error:
   Postal Code Region Mismatch
   Saving not possible due to status of document

You configured an external tax provider.

There can be 2 causes of this error:

• The State/RegionCode of the Address in the Sales Order is not maintained.
• The Postal Code/Zip Code and the State/Region Code maintained in the Address does not match. 

Once you configure an external tax provided, you have to make sure that all the addresses within the system are correct, especially the postal and region codes (e.g State and Zip Code/Postal Code) should be in sync because the external tax provider validates all the addresses being sent to it.

To solve the issue you need:

• Correct the Addresses in your Account Master Data and ensure that for all Addresses the State/Region Code and Postal Code/Zip Code are maintained and correct.
• Cancel the Sales Order XYZ and all follow up documents. Then create a new Sales Order (not a copy of Sales Order XYZ) with the correct data and complete the process.
• Once the Sales Order XYZ and all follow up documents were canceled create an Incident with reference to this issue and all details such as Sales Order ID and performed changes send the Incident to SAP.

We can cancel the process communication message.
