Hi,

Just check the documentation on Create DATA.

SIMPLETYPE Type Declarations in the CREATE DATA Statement

check this..

DATA: len TYPE i. 
... 
TypeName = 'C'. 
i = 36. 
... 
CREATE DATA dref TYPE (TypeName) LENGTH len.

Hi,

Use like this,

CREATE DATA ls_struct TYPE (lv_struct).

The above statement creates a structure what ever value the variable lv_struct currently holds.

Hi ,

Creating variables dynamically.

You can use the statement Create data. This allows you to create fields in a pre-defined or user-defined data type. The statement has following variants:

Create Data dref Type typ.

Create Data dref Type (typename).

Create Data dref Like field.

Create Data dref Type Line of Itab.

Create Data dref Like Line of Itab.

Eg :

PARAMETERS:

tab_name TYPE tname, "Table name

tab_comp TYPE tfieldname, "Field name

line_num TYPE i DEFAULT 10. "Line number

FIELD-SYMBOLS:

<wa> TYPE ANY,

<comp> TYPE ANY.

DATA:

wa_ref TYPE REF TO DATA.

CREATE DATA wa_ref TYPE (tab_name). "Suitable work area

ASSIGN wa_ref->* TO <wa>.

SELECT * FROM (tab_name) INTO <wa>.

CHECK SY-DBCNT < line_num.

ASSIGN COMPONENT tab_comp OF STRUCTURE <wa> TO .

WRITE: / tab_comp, .

ENDSELECT.

In the above example, the content of a specific field of a database table is read, whereby the field and table names are not known until runtime.

you try something like this:

DATA: my_dyn_var TYPE REF TO data,

my_dyn_vars TYPE REF TO data.

FIELD-SYMBOLS: <my_vars> TYPE table,

<my_var> TYPE ANY.

Create the single variable as MY_TYPE

CREATE DATA my_dyn_var TYPE (my_type).

ASSIGN my_dyn_var->* TO <my_var>.

Create n variables as MY_TYPE:

CREATE DATA my_dyn_vars TYPE STANDARD TABLE OF (my_type).

ASSIGN my_dyn_vars->* TO <my_vars>.

DO n TIMES.

APPEND <my_var> TO <my_vars>.

ENDDO.
