How to find no. of days,subtract date -- need help 04/21/2008 - 11/05/2007

Question

ADAT is internally YYYYMMDD format in table.
Should i move this field before computation ? IF SO WHAT IS THE FORMAT ,statement pls;
G_days = ITAB10-ADAT - ITAB11-ADAT.
04/21/2008 - 11/05/2007 ouput is 54.   ---THIS OUTPUT IS WRONG.
Any better way of doing this.
second value 11/05/2007 - 09/10/2007 ouput is 86
SORT ITAB9 BY ADAT DESCENDING.
APPEND LINES OF ITAB9 FROM 1 TO 7 TO ITAB10.
DELETE ITAB9 INDEX 1.
APPEND LINES OF ITAB9 FROM 1 TO 7 TO ITAB11.
For eg. : if  02/30/2008 - 02/10/2008 -
ouput should be 20 days..

Hi,
Check the following code:
REPORT ZDATEDIFF.
DATA: EDAYS   LIKE VTBBEWE-ATAGE,
      EMONTHS LIKE VTBBEWE-ATAGE,
      EYEARS  LIKE VTBBEWE-ATAGE.
PARAMETERS: FROMDATE LIKE VTBBEWE-DBERVON,
            TODATE   LIKE VTBBEWE-DBERBIS DEFAULT SY-DATUM.
call function 'FIMA_DAYS_AND_MONTHS_AND_YEARS'
  exporting
    i_date_from          = FROMDATE
    i_date_to            = TODATE
  I_FLG_SEPARATE       = ' '
  IMPORTING
    E_DAYS               = EDAYS
    E_MONTHS             = EMONTHS
    E_YEARS              = EYEARS.
WRITE:/ 'Difference in Days   ', EDAYS.
WRITE:/ 'Difference in Months ', EMONTHS.
WRITE:/ 'Difference in Years  ', EYEARS.
INITIALIZATION.
FROMDATE = SY-DATUM - 60.
