3154612 - Fiori Confirm Quanity and Price App creates wrong quantities in goods receipt if part of PO already invoiced in SAP Invoice Management by Open Text

In SAP Invoice Management by Open Text, using Fiori Confirm Quanity and Price App, GR (goods receipt) quantity posted from the Fiori App is incorrectly calculated, when PO is already partly invoiced.

Example:
- PO with 10 items
- create invoice #1 for 3 items
- run exception and let VIM create GR for 3 items (Quantity as invoiced)
- create invoice #2 for 4 items
- process exception in Fiori (Quantity as invoiced): The algorithm just creates GR for 1 item
It is not taken into account that 3 items received have been invoiced already.
As a result the invoice remains blocked with no user assigned.
