Modification 1

Temporal Hierarchies

The new addition PERIOD of the statement DEFINE HIERARCHY can now be used to create temporal hierarchies in which the hierarchy nodes are limited by time intervals.

Modification 2

Annotation for Database Hints

Modification 3

Annotations for Releasing Elements

The new element annotations

• @API.element.successor
  

can be used to override releases of the individual elements and successors can be specified for forbidden elements.

Modification 4

CAST Matrix Revised

The matrix of types that can be converted to each other using a CAST expression was revised In particular, the new data types in ABAP Dictionary are respected. The new types DECFLOAT16 and DECFLOAT34 can also be specified after the addition AS of the aggregate function AVG.
