Dynamic casting in field symbol assignment

[Former Member]

Dear experts,

I'm studying about dynamic casting with field symbols.

ASSIGN sy-datum TO <any> CASTING TYPE (typename).

Should the typename in my code above be a name of a type in the dictionary? I tried to use 'c' and 'i' as the value of typename (elementary type) but it raises run-time error.

Regards,

Press F1 on CASTING TYPE and you can find what it means

Hi,

When the system accesses the field symbol, the content of the assigned data object is interpreted as if it had the type declared in the statement. After the TYPE addition, you can declare the name of a data object. The content of this data object indicates the data type at runtime.

TYPES: BEGIN OF t_date,
          year(4)  TYPE n,
          month(2) TYPE n,
          day(2)   TYPE n,
       END OF t_date.

FIELD-SYMBOLS: <fs> TYPE ANY,
               <f>  TYPE n.

ASSIGN sy-datum TO <fs> CASTING TYPE t_date.

WRITE / sy-datum.
