What are the most important ABAP classes and FM-s ?

[former_member690323]

Hey Specs

Is there a list of the most important ABAP Classes/ interfaces/ function modules, that a BW/ERP developer most know ?

Why? Every time you need to pick one class or FM, search the forum, not a static list which would probably mean nothing alone.

Hello czeitneraz

It's impossible to tell as the answer depends on the module you're working with, on the topic you're implementing, on the requirements of the topic, etc, etc.

Kind regards,

czeitneraz,

Usage of Classes, FMs etc are clearly based on the requirement you receive and not dependent on the modules. You cant restrict your user's required specific to modules.

Each Class, FMs has unique functionality and when you are in need of that you ought to use that. Functionalities are not distributed across with different names for different modules, they are all one and same for all.

Hello czeitneraz

If you are looking for interfaces, I'd definitely start with BAPI transaction that lists all business API.

For SOAP / OData API go to SAP API Hub

Really there is no point in chasing "all" FM / classes / interfaces unless you know your requirements.

Tell us what you need to do and SAP Community will help.
