..: Update Status under re-construction..
Huh... I'd rather not follow you down that rabbit hole. Just one thing: why would you? Create complex prefix rules that don't really have any practical utility?
The Z or Y is a given (unless you have a reserved namespace to work with, but that's a different topic). But why additional prefixes? You'll never risk confusing a domain with anything else, nor a report.
And when it comes to variable/parameter naming, I would strongly suggest searching this wonderful place for entries discussing "Hungarian notation" and/or a visit to the Clean ABAP styleguide.
1990s called, wanted their naming conventions back...
Enough of this prefix nonsense, seriously, folks. Especially ZDOM business just makes no sense whatsoever. You know it's a domain by looking at it.
+1 to Rainer on Clean ABAP. And some more thoughts on the guidelines from me: https://blogs.sap.com/2021/04/27/are-your-abap-guidelines-misguided/
Did you really refer to the namespace of documentation "Mobile Application Studio"?
