R12.2.8 Payables - Invoices - Distributions - View PO

Hi, we are currently upgrading from R12.1.3 to R12.2.8 and while testing in Payables - Invoice workbench - All Distributions - View PO I noticed that the PO lines display is not the same.

-     In R12.1.3 when you hit VIEW PO you get to the Purchase Order Shipments and then hit the Distributions Button to get to the Purchase Order Distributions.

-      In R12.2.8 when you hit VIEW PO you get directly to the Purchase order Distributions and the Purchase Order Shipments part is missing.

Is this new for R12.2.8?

I attached screenshots.

Many thanks for your comments.
