Released ABAP Classes - Complete Reference

Source: https://github.com/SAP-samples/abap-cheat-sheets/blob/main/22_Released_ABAP_Classes.md

Version Note: Released ABAP classes are primarily for ABAP Cloud development. int8 type and cl_abap_bigint=>factory_from_int8 require 7.50+. On 7.40, use type i or p for integer operations.

Overview

Released ABAP classes are part of SAP's official APIs for ABAP Cloud Development.

Query Released Classes

SELECT ReleasedObjectType, ReleasedObjectName, ReleaseState
  FROM i_apisforclouddevelopment
  WHERE releasestate = 'RELEASED'
  AND ReleasedObjectType = 'CLAS'
  INTO TABLE @DATA(released_classes).

Find Successors for Deprecated Objects

SELECT *
  FROM i_apiswithclouddevsuccessor
  INTO TABLE @DATA(successors).
