Syntax
CLASS-METHODS meth FOR TABLE FUNCTION cds_entity.
Effect
This statement declares the static method meth as an
AMDP function implementation that implements a
CDS table function cds_entity as an
AMDP table function. This statement can only be specified in the
public
visibility section of an
AMDP class and not in an interface. The method must
be implemented using the addition BY DATABASE FUNCTION of the statement METHOD.
cds_entity expects a CDS table function defined using the statement DEFINE TABLE FUNCTION in the
ABAP CDS
CDS DDL. For this function,
the current class and the method meth must be specified after the addition IMPLEMENTED BY METHOD.
No other additions are possible. The interface parameters in the AMDP function implementation are added to the CDS table function as follows:
- Mandatory input parameters of the AMDP function implementation are generated from the input parameters of the CDS table function. The names are copied and the ABAP types are derived from the dictionary types.
-
A return value of the type of a standard table with empty table key with the name
resultwith a structured row type is generated from the elements of the CDS table function. The names of the components of the row type correspond with the names of the elements, and the data types are derived from their dictionary types.
