CASTING in ABAP

light111CASTING in ABAP

 CASTING allows to assign value from one type to another generic type by specifying the target type during assignment. The below program shows some assignments.


DATA: lv_date TYPE d.
lv_date = sy-datum.
WRITE:/ lv_date.
//—————–//
FIELD-SYMBOLS: <fs_date1> TYPE d.
* lv_date & <fs_date1> are fully typed & compatible
* so no CASTING required, just simply ASSIGN
ASSIGN lv_date TO <fs_date1>.
WRITE:/ <fs_date1>.
//—————–//
TYPES: BEGIN OF ty_date,
yy(4),
mm(2),
dd(2),
END OF ty_date.
FIELD-SYMBOLS: <fs_date2> TYPE ty_date.
* lv_date & <fs_date2> are fully typed but not compatible
* so need CASTING but not type specification
ASSIGN lv_date TO <fs_date2> CASTING.
WRITE:/ <fs_date2>.
//—————–//
* lv_date is fully typed but <fs_date3> is generic so not compatible
* so need CASTING with exlicit type ( build in type)
FIELD-SYMBOLS: <fs_date3> TYPE any.
ASSIGN lv_date TO <fs_date3> CASTING TYPE d.
WRITE:/ <fs_date3>.
//—————–//
* lv_date if fully typed but <fs_date4> is generic so not compatible
* so need CASTING with exlicit type ( user defined type)
FIELD-SYMBOLS: <fs_date4> TYPE any.
ASSIGN lv_date TO <fs_date4> CASTING TYPE ty_date.
WRITE:/ <fs_date4>.
//—————–//
