Note the examples in the rap branch of the ABAP cheat sheets GitHub repository. RAP Behavior Definition Language Highlights key features and syntax options of the RAP Behavior Definition Language (BDL) for designing RAP behavior definitions (BDEF) The ABAP cheat sheets GitHub repository features simplified, non-semantic demo RAP business objects (BOs) in the rap branch for exploring a selection of various RAP-related features, syntaxes and concepts in simplified, non-real-world contexts. Topics include managed and unmanaged RAP BOs, draft-enabled RAP BOs, numbering concepts like early and late numbering, field-specific characteristics, standard operations (CRUD), actions as non-standard operations, authorizations, local RAP business events, and more.
