ASSIGN for Dereferencing

Variant 5

ASSIGN dref->* TO <fs>.

Additions

1. ... CASTING ... or
2. ... TYPE type
3. ... DECIMALS dec
4. ... RANGE r

Effect

The field to which the data reference dref is pointing is assigned to the field symbol <fs>. At runtime, the field symbol <fs> points to the same contents as the data reference dref. If the field symbol <fs> is not typed(FIELD-SYMBOLS),it adopts the type and attributes of the field to which dref is pointing. otherwise, the system checks whether the type of the field is compatible with the type of the field symbol <fs> when you make the assignment.

Note

If the data reference variable is fully typed - that is, if it does not have a generic type - the expression dref->* can also be used in other ABAP statements in any operand position.

Return Value

SY-SUBRC = 0:

Assignment successful

SY-SUBRC = 4:

Assignment not successful. The data reference was invalid.

Example

DATA: dref TYPE REF TO DATA.
TYPES: booking TYPE sbook.
FIELD-SYMBOLS: <fs> TYPE ANY.

CREATE DATA dref TYPE booking.
ASSIGN dref->* TO <fs>.

In this example, CREATEDATA is used to create an anonymous data object to which the reference dref points. Its type is that of the work area of the database table SBOOK. The data object is then assigned to the field symbol <fs> using the dereferencing operator ->*You can now work with the field symbol in the normal way.

Exceptions
