SAP S/4HANA

What is Custom Fields and Logic?

S/4HANA Fiori apps that let key users add fields to business contexts and implement cloud BAdIs in a restricted ABAP language.

Custom fields can be exposed on UIs, reports, forms, and APIs from a single definition. Custom logic implements released BAdIs with a limited, upgrade-safe ABAP subset. Both are key-user extensibility tools and require regression of the affected forms and interfaces.
