I've been using the FM calculate_date and detected that this FM producers wrong dates in some cases. SAP declares this FM as internal use only and will not fix the problem.

I'm now a little bit in trouble of finding an <b>official</b> FM module doing date calculations, does anybody know some of those? please do not post FM which are declared as internal use, i will not reward points on those useless answers.

Hi Rainer,

If you want to add or subtract a number of days from a date.

Use date1 = date1 + 30.

this will add 30 days to the date1.

or use date2 = date2 - 10.

this will give a date 10 days prior to date2.

<b>Reward points, if helpful.</b>

Regards,

Atin

i think you are trying to add months and days with a date. If i am not wrong you can do like this... it may work


data : vdate like sy-datum.

vdate = sy-datum.

CALL FUNCTION 'MONTH_PLUS_DETERMINE'
  EXPORTING
    months        = '+3'
    olddate       = vdate
 IMPORTING
   NEWDATE       = vdate
          .

vdate = vdate + 5.

write : / vdate.

here i am adding 3months and 5 days with the current date.

vdate must be type d.

I don't know of any released date calculation FMs. Unreleased FMs are the meat and potatoes of ABAPERS,

But date arithmetic isn't that difficult. Why don't you just wite your own routine? What exactly are you trying to calculate?
