Abap Exception categories

[niuniuch]

It's 2023 and it's time to rewrite the section on exception categories (or remove it completely if you think it's not a settled subject) because in it's current state is causing harm.

Robert Martin said it already in 2001, and in 2023 it's clear as dailight.

1. Use CX_NO_CHECK.
2. In exceptional cases, when you want customers of your software to acknowledge exceptions that it might throw, consider wrapping a CX_CHECK exception around them in your public API layer (for example when developing a code library for sale).
3. Never use CX_DYNAMIC_CHECK, as it's just an checked exception that can't be caught by it's name, it's always better to just use CX_NO_CHECK

There's already a discussion about the same topic from 2020 that's unfortunately still open: #138

I suggest you either add a comment to that discussion or open a pull request to facilitate a faster discussion? 😉

Thanks for pointing that out, I added a comment in #138.
I guess what is an exceptional case for me, might be the usual case for others. It all depends on what kind of code you're working on...

Closing this since the main discussion is in #138
