The currency for a Purchase Order in the Supplier Invoicing workcenter is ABC but when you try to create a new invoice with respect to that purchase order it will automatically take the currency as XYZ instead of ABC.
Reproducing the Issue
- Go to the Supplier Invoicing workcenter.
- Go to the Invoice Entry view.
- Select All Orders in the drop down show list and select your Purchase Order
- Select Go - It shows the currency ABC.
- Select New invoice.
The system automatically picks currency XYZ.
This happens when an invoice was already posted for this Purchase Order with a deviating currency -you can check this in the Document Flow tab of the Purchase Order
The system then proposes the same currency for all subsequent Invoices.
The idea behind this behaviour is that the currency the supplier uses in his invoices may be different from the currency of the purchase order and the system assumes that a supplier always creates his invoices with the same currency.
This is only a proposed default currency when the invoice is created and the field can be edited manually if needed.
