Findind Data type of a variable in Run Time

Question

Hi Experts,
    I am trying to find the data type of variable in runtime with "DESCRIBE FIELD" statement.
    but it always shows data type C by default. i have written this code.....
    DATA: w_value TYPE d.
    DESCRIBE FIELD p_value TYPE w_value.
   My requirement is that if  i pass a variable of any type(like date, time , char, Integer , Decimal etc.) from selection screen i  will   give the correct data type of variable.
Please let me know how to acheive this problem.

Hey Raj,
In this code it always ask a date type variable.
Still my problem i snot getting solve.
check the below one which might give u a fair idea
DATA: Desc_object         TYPE ref to cl_abap_typedescr.
Parameters:   p_char           TYPE char10 ,
              p_date           TYPE d,
              p_int            type i.
Field-symbols : <any_type> type any.
START-OF-SELECTION.
  If p_char is not initial.
     assign p_char to <any_type>.
  elseIf p_date is not initial.
     assign p_date to <any_type>.
  elseif p_int is not initial.
     assign p_int to <any_type>.
  endif.
IF <any_type>  is assigned.
  desc_object = cl_abap_typedescr=>describe_by_data( <any_type> ).
  WRITE: / desc_object->absolute_name.
  WRITE: / desc_object->type_kind.
ENDIF.
The Catch lies in assigning the variables to field symbol. I think you already have that part of code
