Modification 1

CDS Annotations

The following enhancements have been introduced for CDS annotations:

Annotations in a SELECT list of a CDS view can now be entered after an element. Before the name of an annotation, @< must be written instead of @.
A new syntax with square and curly brackets makes it possible to use value lists and annotation lists as value specification after the colon of an annotation specification.
The new ABAP annotation AbapCatalog.compiler.compareFilter can be used to specify whether the filter conditions are compared for the path expressions of a view. In this case, the associated join expression is evaluated once only, if the same filter condition occurs.

Modification 2

CDS Views with Parameters

In the statement DEFINE VIEW, input parameters can now be defined for CDS views that can be used in operand positions in the view.

When using a CDS view with parameters in a CDS view or in Open SQL, the input parameters must be given actual parameters; new additions are available for this in shape of parenthesized, comma-separated lists in the statements SELECT of the DDL and SELECT of Open SQL.

Modification 3

CDS View Enhancements

The new statement EXTEND VIEW of the DDL of the ABAP CDS makes it possible to add new view fields to existing CDS views - without making changes - by using CDS view enhancements.

Modification 4

Expressions and Functions

The following enhancements have been implemented:

Division with operator / is now supported in arithmetic expressions.
The following new predefined functions have been added:

String functions CONCAT and REPLACE

Numeric functions ABS, DIV, DIVISION, FLOOR, MOD, and ROUND

The new coalesce function has been added.
In addition to simple case distinction, complex case distinction (searched case) is now also available.
The special conversion functions UNIT_CONVERSION, CURRENCY_CONVERSION, and DECIMAL_SHIFT enable unit conversions and currency conversions.

Modification 5

Join Type for Associations

The new attributes INNER and LEFT OUTER for an association of a path expression enable to declare explicitly in which join the association is performed.

Modification 6

Path Expressions with Filter Conditions in Conditions

The new addition 1: before a filter condition of a path expression declares this condition as monovalent and enables the path expression to be used in a WHERE clause or HAVING clause.

Modification 7

Checking Literals Against Fixed Values of Domains

The new syntax #domain.literal enables literal values literal of a CDS view to be checked against the fixed values of a domain.
