S/4HANA on-premise: Purchase Requisition app links to Material app.. which doesn't exist on S/4

I've got the "Manage Purchase Requisitions" apps working in S/4HANA on-premise:

There appears to be a link on the Item Description "Ale for Party (1)", so curiosity causes me to select this:

Within a split second this error pops-up and closes, and I'm landed back to where I was.

When I check the console in the Chrome Developer Tools, to find out what app tried to load, I find the following:

So I can see here the target that was atempting to load was "Material-displayFactSheet?Material=1" so I try to call this URL directly, and get an error.

So I look for a "Material" app in the Fiori Apps Library, and find this, as the only likely contender.. but this is not for S/4HANA on premise, and when I check SICF for the ICF node for this UI5 app I find, as expected, it doesn't exist.

I looked through all the S/4HANA apps with the word "material" in the tile for the matching Semantic Object = Material and Action = displayFactSheet, but none exists...

Is there a way what a user can view this information? or is the hyperlink a mistake? Myabe the intention is what we manually create a new target to point to a Business Client 6.0 screen, or a WebGui screen, rather than a Fiori app, but it seems somewhat unfair to give a link with no mapping to a target.

Am I missing something?

Thank you
