Leap year issue

Former Member — Wed, 07 Jan 2009 11:39:55 GMT

Hi friends,

I have a problem in one of the existing codes.

The cancellation amount is calculated for a range of dates.

Say the active line item has a start date of 01.03.2006 and end date of 01.03.2012 say (B).

Now if a rejection/Cancellation is put on date 01.05.2007 (A), the current program is calculating a value

based on the diffrence of days (B - A).

then this cancelled amnt = the no of cancelled days * (a constn value * 12 / 365).

Now I want to modify my logic in such a way that the leap is also accounted.

If I use the same dates , i realise that 2008 is the leap yr.

So how can i modify my calculation for the range if it contains a leap yr.

Please suggest something on this, as it will be really helpful.

Thanks,

Sapna Agarwal

Hi Sapna,

Instead of using the B-A concept for calculating the date difference use the function module " /SDF/CMO_DATETIME_DIFFERENCE " which gives the difference between two dates and this also takes the leap year into consideration.

Hope this will solve your problem.

HI,

use this function module.

/SAPNEA/JSC_LEAP_YEAR.

Hi,

Try this: HR_99S_INTERVAL_BETWEEN_DATES

Refer:

Hi,

you can use the FM HR_HK_DIFF_BT_2_DATES with output_format = '02' to get the difference between dates in days.

Hi,

Try using any of these function modules LEAP_DAYS_BETWEEN_TWO_DATES' or FIMA_LEAP_DAYS_BETWEEN_2_DATES.

Or try using this simple logic to find if a date is leap or not..

DATA: date1 TYPE d.

date1 = '20040301'.

date1 = date1 - 1.

IF date1+6(2) = '29'.

WRITE 'A leap year'.

ELSE.

WRITE 'No leap year'.

ENDIF.

Hello friends,

Thanks for the response on my issue.

The leap year is not the only issue I am facing.

The calculation discussed:

then this cancelled amnt = the no of cancelled days * (a constn value * 12 / 365).

Will also need a change now.

Because if the the division by 365 will be now 366 for a leap year.

But if this is for a range of 2 or 3 yrs in which 1 yr is a leap yr and the other 2 are non leap yrs, then how can i do the calculation.

Regards,

Sapna

Hi Sapna,

try to use the FM /SDF/CMO_DATETIME_DIFFERENCE, it will take care of the leap year, just pass the two dates for which you want the difference.

CALL FUNCTION '/SDF/CMO_DATETIME_DIFFERENCE'
 EXPORTING
   DATE1                   = s_date
*   TIME1                  =
   DATE2                   = e_date
*   TIME2                  =
 IMPORTING
   DATEDIFF                = DATEDIFF
*   TIMEDIFF               =
*   EARLIEST               =
 EXCEPTIONS
   INVALID_DATETIME        = 1
   OTHERS                  = 2

IF sy-subrc <> 0.
 MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

if the gap is for more one year than you have to do the calculation year wise only, in this case use the fm '/SAPNEA/JSC_LEAP_YEAR' that which year is a leap year. And than go for a IF condition while calculating either it should be 365 or 366 days.

With luck,

Pritam.
