We will use the example of a Sales Order:

1. Go to the Sales Orders Work Centre.
2. Go to the Sales Orders View.
3. Show All Orders and enter XXX in the Find Field (XXX represents the ID of the Sales Order).
4. Navigate to the Items Tab.
5. Select a line item and navigate to the Taxes sub tab. 
6. You can see that a VAT number is maintained for the Customer’s Tax registration information.

The error occurs because the VAT number maintained in the Sales Order is an old VAT number which is no longer maintained in the account master data. The VAT number was since changed in the account master data.

1. Go to the Sales Orders Work Centre.
2. Go to the Sales Orders View.
3. Show All Orders and enter XXX in the Find Field (XXX represents the ID of the Sales Order).
4. Click on View All.
5. Perform a dummy change with any of the data of the Sales Order.
6. Click Save.

The Save will re-trigger the tax determination and the error will be resolved.
