DATA - BEGIN OF

Syntax

DATA BEGIN OF struc [READ-ONLY].
  ...
  {DATA comp ...} | {INCLUDE {TYPE|STRUCTURE} ...}.
  ...
DATA END OF struc.

Effect:

The declaration of a new structure struc is opened using a DATA statement with the addition BEGIN OF and must be ended using a DATA statement with the addition END OF.

Within these two DATA statements, any DATA statements, particularly any further closed structures, and the statements INCLUDE TYPE and INCLUDE STRUCTURE can be included. The meaning of these statements is the same as in the definition of structured data types in the section TYPES - BEGIN OF, but here it is used to generate a bound structured data type. No structure can be created without at least one component.

Notes

The addition READ-ONLY is only possible for the whole structure, and not for individual structure components comp.

A structure cannot have the name text as this is reserved for addressing test symbols.

Example:

In this example, a structure spfli_struc is declared with an elementary component index and a substructure spfli_wa. The SELECT loop shows one possible use of the nested structure.

DATA: BEGIN OF spfli_struc,
         index    TYPE i,
         spfli_wa TYPE spfli,
      END OF spfli_struc.

SELECT *
       FROM spfli
       INTO spfli_struc-spfli_wa.
  spfli_struc-index = spfli_struc-index + 1.
  WRITE: / spfli_struc-index,
           spfli_struc-spfli_wa-carrid,
           spfli_struc-spfli_wa-carrid.
ENDSELECT.
