How are Confirmation comments/records sorted in S/4HANA?

[AkikoKono]

Hello, experts!

This is question about a scenario where a supplier submits an Order Confirmation with multiple delivery dates for a single schedule line.

The supplier initiates this by clicking the "Split" button on the "Order to Confirm" tile, inputting multiple dates and comments before submission.

Based on our observations in our environment, the supplier's response is integrated into the S/4HANA Purchase Order in the following manner.

We would like to confirm if this is standard functionality:

1. Comments: The confirmation comments at schedule line level are sorted alphabetically and concatenated in the PO item text.

2. Dates and Quantities: The confirmation records in the PO Item Confirmation tab (EKES table records) are sorted by delivery date.

Additionally, if this is indeed standard behavior, we notice that the sequence of items in points 1 and 2 may not align. Is there a way to synchronize these sequences?
