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, in cases when a CDS association is used more than once, the filter conditions are compared for the path expressions of a view. If the filter condition has identical semantics, the associated join expression is created only once in the variant of the view on the database.
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 ABAP 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 ABAP SQL.
CDS View Extensions
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 DDIC-based view extensions.
Expressions and Functions
The following enhancements have been implemented:
- Division with operator / is now supported in arithmetic expressions.
- The following new built-in 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.
Join Type for CDS Associations
The new attributes INNER and LEFT OUTER for a
CDS association of a
path expression enable to declare explicitly in which join the CDS association is performed.
Path Expressions with Filter Conditions in Conditions
The new addition 1: before a
filter condition of a
path expression declares this condition as
unique and enables the path expression to be used in a
WHERE clause or HAVING clause.
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 DDIC domain.
