how to find the previous months date from teh current date

[Former Member]

Dear All,

Am working on a 3.1 i version.

Please let me know how i need to find the previous months date from the current date.

i mean current date- 1 month .

This logic will work.

data : w_date like sy-datum.

w_date = sy-daum.

"The statement below will work for everything....

w_date = w_date - 30.

write w:date.

But please tell me how thisis to be handled in case of today.

today being 30th march ,how do i find the one month old date.

Regards,

Abaper.

Hi,

Use the FM 'CALCULATE_DATE' if it exists in your version.

check if this FM exists in ur system: HR_99S_DATE_ADD_SUB_DURATION

[rainer_hbenthal]

Set the day of your date field to '01' and subtract then 1 from the date. Now you will have the month in the5th and 6th position without taking care of leap years and year end problems.

Its not suitable for every condition...

DATA : w_date LIKE sy-datum.

w_date = sy-datum.

w_date+4(2) = w_date+4(2) - 1.

WRITE: sy-datum, / w_date.

[rainer_hbenthal]

Are you sure this is working for January?

Heres mine:

wa_date+6(2) = '01'.
wa_date = wa_date - 1.
write:/ wa_date+4(2).

Works with leapyears and years end/start.

Hi,

Use FM NUMBER_OF_DAYS_PER_MONTH_GET to get Total number of days in any month of year.

than Minus these from your date using your logic above.

Hope this will solve out your Problem,

hi all,

This does not work for todays date 30-03-2009.(as o jave told earlier. Thisis my major problem)

w_date = sy-datum.

w_date4(2) = w_date4(2) - 1.

WRITE: sy-datum, / w_date.
