ABAP_DDIC_DDL - EXTEND TYPE
ABAP_SYNTAX structure_annos EXTEND TYPE struct$|dbtab WITH append_struct { ... component $[... extend ...$]; ... include; ... }
What does it do? Dictionary DDL statement for defining an ABAP Dictionary append structure append_struct in the ABAP Development Tools .
The statement EXTEND TYPE adds the append structure append_struct either to an existing structure struct or to a DDIC database table dbtab.
The mandatory properties of the append structure must be specified in front of the statement EXTEND TYPE using the same annotations structure_annos as in the definition of a structure.
As in the definition of a structure using DEFINE STRUCTURE, the components of the append structure are defined in a semicolon-separated list in curly brackets { }, either as individual components component or by including include structures include.
As when including structures, an assignment to a search help and a definition of a foreign key dependency can be overwritten using the addition extend in a blank-separated list.
Latest notes:
As in the CDS syntax, the definition of an ABAP Dictionary append structure can contain comments after // and between /* ... */.
A more detailed description of the syntax is available in the ADT documentation Syntax of ABAP Dictionary Objects . ABAP_HINT_END
Example ABAP Coding
Adds the append structure DEMO_APPEND_STRUCTURE to the structure DEMO_STRUCTURE in the ADT. @EndUserText.label : 'Demo append structure' @AbapCatalog.enhancement.category : #EXTENSIBLE_CHARACTER_NUMERIC extend type demo_structure with demo_append_structure { comp3 : dats; comp4 : tims; } The source code used to define the structure DEMO_STRUCTURE is not modified by this extension. In the ADT, however, an icon indicates that the structure is extended using DEMO_APPEND_STRUCTURE. ABAP_EXAMPLE_END
