Knowledge Management

Question:
Can any one help .....
according to the requirement Currently I am adding 1095 days to system date, but in between there will be a leap year , so I need to check wether leap year exsists or not ? Can you tell me how to check ? as this looks simple but I am new to technical and If better give me the code ,
Currently the code is like below :
DATA: P_DATE LIKE SY-DATUM,
P_DATE1 LIKE SY-DATUM.
P_DATE1 = P_DATE + 1095.
Thanks
Rajiv
Answer:
If you just want to add 3 years (there can either be one leap year or no leap year):
P_DATE1 = P_DATE + 1095.
IF P_DATE1+4(4) NE P_DATE+4(4).
ADD 1 TO P_DATE1.
ENDIF.
Answer:
P_DATE1 = P_DATE + 1095
Surely SAP will automatically take leap years into consideration when calculating p_date1

Thank you very much for quick reply , Can you tell me this logic works for both leap year & normal year as well?

Keep it simple: P_DATE1 = P_DATE + 1095

Hello friend, I have cross checked the statement what you have said. and it does not happen automatically. if you add 3 to the date(4) , the year gets updated and not the date. You verify yourself to confirm yourself......
thank you,

Rajiv never said he/she wanted to add 3 years, he/she said 1095 days !

Answer:
there are many checks, remember Y2k?
ok heres a simple onem not the most elegant but u get my point
its about 3 years...
take each of these years in a do loop or whatever , maybe FM it...
your variable is w_date type datum value 31.03.2004
subtract 1 from this into another date field variable?
is the result the 28th or the 29th
there is also the divide by 4/400 rule..
take ur pick

Answer:
I don't think HL's suggestion will work - I think you could end up with a month 15 using that.... it's worth checking (not at my system right now to verify it) but I would consider the previous suggestion to be more worthy.
No, but you could enfd up with an invalid date, say if the start date is 20000229.

IF P_DATE1+4(4) NE P_DATE+4(4).
ADD 1 TO P_DATE1.

As long as you always want to add 3 years, this will work.
If you want to add 6 years, there yould be either one or 2 leap years in the interval, so you would have to do some adjustment, e.g.
p_date1 = p_date + 6571. " ( 6 * 365 + 1)
IF P_DATE1+4(4) NE P_DATE+4(4).
ADD 1 TO P_DATE1.
ENDIF.
