For scope item 'Automation of Source-to-Pay with Ariba Network (42K)', configuration has been set as "Always park supplier invoice" in S/4Hana Public Cloud, however invoices from Ariba are failing. 

SAP S/4Hana Cloud Public Edition

1. Configure scope item 42K to always park supplier invoice (Configuration Activity 103263:Settings for Parking of Supplier Invoices).
2. Create Purchase order with GR based invoice verification.
3. Create supplier invoice with Ariba (API InvoiceRequest_In).
4. Invoices are failing instead of parking. 
5. Error message is: 'Item 00010 for purchasing document x not selectable'.

This is standard system behaviour. 

The program stops with error 'Item 00010 for purchasing document x not selectable', as purchase orders are not in released status. 

Generally, it is not possible to invoice a purchase order before it is released. 
Also, if GR-based Invoice verification is set, and there is no existing GR, it is not possible to invoice the purchase order.

Release the purchase order and enter a GR. Alternatively based on business requirement, the GR-based invoice verification could be unmarked so invoice can be parked or posted to the purchase order.
