How To Use Constructor Operator VALUE

Constructor operator VALUE constructs a value for a specified type.

The syntax for the VALUE constructor expressions is as follows:

... VALUE dtype|#( ... ) ...

This will construct a variable of type type with the initial value.

Create A Variable

Variables can be constructed like this:

* int
DATA(int) = VALUE i( ).
  
* float
DATA(float) = VALUE f( ).
  
* DDIC type MATNR
DATA(matnr) = VALUE matnr( ).

Create A Structure

Structures can be constructed like this where for each component a value can be assigned:

… VALUE dtype|#( comp1 = a1 comp2 = a2 … ) …

TYPES: BEGIN OF ty_sflight,
         carrid TYPE sflight-carrid,
         connid TYPE sflight-connid,
       END OF ty_sflight.
 
DATA(sflight) = VALUE ty_sflight( carrid = 'LH'
                                  connid = '0123' ).
 
* DDIC type BAPIMATHEAD
DATA(bapimathead) = VALUE bapimathead( ).
 
* DDIC type BAPIMATHEAD with values
DATA(bapimathead) = VALUE bapimathead( material      = '1234567890'
                                       basic_view    = abap_true
                                       purchase_view = abap_true
                                       account_view  = abap_true ).

Create An Internal Table

Internal Tables can be constructed like this where for each line a value can be assigned:

… VALUE dtype|#( ( … ) ( … ) … ) …

TYPES: BEGIN OF ty_sflight,
         carrid TYPE sflight-carrid,
         connid TYPE sflight-connid,
       END OF ty_sflight.
 
TYPES: tt_sflight TYPE STANDARD TABLE OF ty_sflight WITH DEFAULT KEY.
 
DATA(sflight) = VALUE tt_sflight( ( carrid = 'LH' connid = '0123' )
                                  ( carrid = 'AA' connid = '3210' ) ).
 
* DDIC type STRINGTAB
DATA(stringtab_empty) = VALUE stringtab( ).
 
* DDIC type STRINGTAB with values
DATA(stringtab) = VALUE stringtab( ( `Hello` )
                                   ( `World` ) ).
