Modern ABAP Syntax for Classic ABAP Developers: Inline Declarations, Constructor Expressions and New Open SQL

A bridge for developers who learned ABAP on ECC: inline declarations and FINAL, string templates, VALUE, CORRESPONDING, REDUCE, FILTER, COND and SWITCH, table expressions and iteration, modern ABAP SQL with strict mode and released CDS views, and the statements ABAP for Cloud Development rejects. Each pattern is shown side by side with the classic form, with the behavior changes that catch refactorings out and the characterization tests that prove a refactoring is safe. Uses Contoso Motor Co.'s legacy core return code.
