SAP Business ByDesign.

Reproducing the Issue

  1.  Go to the Supplier Invoicing work center.
  2.  Select the Invoice Entry view.
  3.  Select All Orders to be Invoiced in the Show field.
  4.  Select a Purchase Order and select the New Invoice button.
  5.  Fill in all the mandatory fields and select the Check button.
  6.  You get the error message: Tax calculation failed.
  7.  The status of the invoice changes to Exception.
  8.  Select the Exceptions tab. You find the exception: Currency <XXX> was not converted to <YYY>. 


Exception is raised due to missing currency exchange rate maintained between your company currency and the supplier currency for the date of the invoice.


So please maintain the exchange rate by following the below steps:

  1. Go to the General Ledger work center.
  2. Go to the Edit Exchange Rate common task.
  3. Maintain the exchange rate between the currencies <XXX> and <YYY> and its validity period.

Once the currency exchange rate is maintained, you need to change the document date to another value and then back to the original value.
