Confirmation of S4HANA and Ariba integration using SCC

[YAMA]

As a premise, I am currently doing a functional test for SCC.

The test contents are as follows.
1. Buyer executes a regular purchase order in S4HANA.
2. Supplier executes order confirmation (delivery date response) in Ariba Bussiness Network.
3. Buyer confirms supplier's delivery date response in S4HANA.
4. Supplier executes shipment notification in Ariba Bussiness Network.

The final "4. Supplier executes shipment notification in the Ariba Bussiness Network. on the Ariba Bussiness Network interface, "Supplier Batch ID", "Country of origin", "Production date", and "date of expiry" are indicated, but the buyer cannot see the entries on the S4HANA screen even if they are entered.

Is the above information for the buyer to confirm on the Ariba Bussiness Network screen, but not on S4HANA?

If there is another way to check, please let me know.
