1254493 - Cannot Post Supplier Invoice. Error while converting <Currency A> to <Currency B>; Contact technical support


 You are unable to post a supplier invoice due to the error message: Error while converting <Currency A> to <Currency B>; Contact technical support. However no currency conversion should take place as both your company and your supplier have the same currency in use.

Reproducing the Issue

  1. Go to the Supplier Invoicing work center.
  2. Select New Invoice Without Purchase Order link in Common Tasks.
  3. Fill in all the mandatory details.
  4. Select Cost Distribution sub tab in the Items tab and select Accounting Type as Cost Center.
  5. Select the cost center given using the value help.
  6. Select the button Post.
  7. You get the above mentioned error message.


The two reasons for this behavior of the supplier invoicing application are: 

  1. There are no currency rates maintained for the currency conversion.
  2. The approval currency maintained in the fine-tune activity Supplier Invoice Approvals differs from the currency in the supplier invoice.


Maintain the Currency Exchange Rates as follows:

  1. Go to General Ledger work center.
  2. Select the link Edit Exchange Rates under Common Tasks.
  3. Select the button Maintain Exchange Rates.

By Default the approval currency for supplier invoice should be the one of your residence in the fine-tuning activity Supplier Invoice Approvals.  

  1. Go to the Business Configuration work center.
  2. Select Implementation Projects view.
  3. Select the Open Activity List  button.
  4. Select Fine tune wizard and select Supplier Invoice Approvals.   
  5. Check the currency maintained here.
