Difference between 2 dates in form of years,months and days.

Hi friends,
i need one function module for finding difference between 2 dates and the output is
no. of years
no.of months
no. of days.
it means the input is begin date and end date
output is no.of years,no.of months and no.of days.
for example begin date is today i.e., 08/02/2008 (dd/mm/yyyy) and end date is 07/03/2008 then the output is
no.of years -
0,
no.of months----
1,
no.of days----
0.
and one more example if begin date 08/02/2008
(dd/mm/yyyy) and end date is 01/02/2008 then the output is
no.of years -
0,
no.of months----
0,
no.of days----
-7..
Please help me it's very urgent

Hi,
Use FM HR_AUPBS_MONTH_DAY.
It Calculate the years, months, days & cal days between 2 dates.
Hi,
The FM is 'FIMA_DAYS_AND_MONTHS_AND_YEARS'
Check the following example:
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.
Also You can write your own function module for this..
just extract day and month and year from the two dates and then get the difference.
suppose date 1 - y1m1d1
date 2 = y2m2d2
data : y1(2) type n,
m1(2) type n,
d1(2) type n,
y2(2) type n,
m2(2) type n,
d2(2) type n,
y1 = date1(4).
m1 = date1+4(2).
d1 = date1+6(2).
y2 = date2(4).
m2 = date2+4(2).
d2 = date2+6(2).
then get the differnce between years and days and months and store them in ur variables
Reward Points if found helpfull..
Cheers,

Tablespace level backup using data pump

Hi,
Im using 10.2.0.4 on RHEL 4,
I have one doubt, can we take a tablespace level backup using data pump,
bt i dnt wnt to use it for transportable tablespace.
thanks.

Yes, you can only for the tables in that tablespace only.
Use the TABLESPACES option to export list of tablespaces.*here all the tables in that tablespaces will be exported*.
and you must have the EXP_FULL_DATABASE role to use tablespace mode.
Have a look at this,

Difference between two dates, using Variables in reporting

how to calculate the days difference between Delivery date and Billing date in reporting, using variables (SAP BW 3.5v)?

Hi,
If you want to do the arethmatioc operations with the date then you will have to declare the date as key figure in the cube and add it there and then update it with the date from R/3.
You can use formula variable for this subtraction.
Create a formula in the bex analyzer and then in the down you will get option for the formula varibale.Just make a replacement path varibale on this time characteristic for which yuou want subtraction.
During creation use "key" in the display and "number" as the data type.
If number is not working them you can use "date" type.
Nothing alse needs to be done during the variable creation.
Once you have made the formula inlcude it in the columns of the report.
Thanks

Difference between two date in bex query

Hi all,
I need to do a difference between two date using formula variable processing type customer exit beaucause I must use factory calendar in the formula.
How can I do it?
Can you give me an example of the routine?
Thanks a lot
Gianmarco

Hi,
You can still use the same code to copy it and customize as per your need. All you need to do is to subract the dates using the class: CL_ABAP_TSTMP after converting to timestamp and resulting seconds you convert back to days....Please get help from the developers to do this...
Also, ensure that you write back this difference value to your variable so you get it on the reports for your calculations...
Cheers,
Emmanuel.

As to the data type of the data type of the difference between two date type of datas

Hi,
I have a question about the data type of the difference between two date type of datas.
There are two date type of datas as:
SSHIPMENTS.RECEIVEDATETIME
SSHIPMENTS.PROMISEDATETIME
I try to use the following SQL Script in Oracle SQL*Plus as:
SELECT CASE
WHEN (SSHIPMENTS.RECEIVEDATETIME - SSHIPMENTS.PROMISEDATETIME) < '000 01:00:00.000' THEN 'OnTime'
WHEN (SSHIPMENTS.RECEIVEDATETIME - SSHIPMENTS.PROMISEDATETIME) < '000 01:30:00.000' THEN '60-89 Minutes'
ELSE '3+ Hours'
END
FROM SSHIPMENTS;
The error message of "Invalid Number" for the '000 01:30:00.000' happens.
I don't know if the data type of the interval is wrong.
Many Thanks,
Cathy

SELECT CASE
WHEN (to_char(SSHIPMENTS.RECEIVEDATETIME,'hhmiss') - to_char(SSHIPMENTS.PROMISEDATETIME,'hh24miss')) < '010000' THEN 'OnTime'
WHEN (to_char(SSHIPMENTS.RECEIVEDATETIME,'hhmiss') - to_char(SSHIPMENTS.PROMISEDATETIME,'hh24miss'))< '000 01:30:00.000' THEN '60-89 Minutes'
ELSE '3+ Hours'
END
FROM SSHIPMENTS;
just try it out..

Difference between doc date,posting date and invoice date

hi bw guys
can someone give a brief on the difference between doc date,posting date and invoice date.and the invidual definitions
thank you

Hi,
Posting Date: Date which is used when entering the document in Financial Accounting or Controlling. The posting date can differ from both the entry date and the doc date.
Document Date: The document date is the date on which the original document was issued. Ex: Inv date, Bill date etc.,
Invoice Date : Usually the date when goods are shipped. Payment dates are set relative to the invoice date.

Difference between Posting Date & Baseline date in MIRO

HI,
What is the difference between Posting Date & Baseline date in MIRO?
Regards
Chandan
Edited by: Chandan H N on Dec 14, 2009 11:11 AM

Dear,
Posting Date:
Posting Date in the Document
Date which is used when entering the document in Financial Accounting or Controlling.
Use
The fiscal year and the period for which an update of the accounts specified in the document or cost elements is made, are derived from the posting date.
When entering documents, the system checks whether the posting date entered is allowed by means of the posting period permitted.
Note
The posting date can differ from both the entry date (day of entry into the system) and the document date (day of creation of the original document).
Baseline Date
Baseline Date for Due Date Calculation
Date to which the periods for the cash discount deadline and the due date for net payment refer. This is the case for line items in open item accounts.
For line items in G/L accounts, the item is due immediately on this date because there are no cash discount specifications.
Procedure
During document entry for open item accounts, the date may be defaulted. For this, a terms of payment key must have been specified in the customer's/vendor's master record for which a default value is requested in the document.
The proposed date can be overwritten.
If the cash discount rates (and days) have not been entered, the baseline date for payment is the same as the due date.

How to consolidate data files using data pump when migrating 10g to 11g?

We have one 10.2.0.4 database to be migrated to a new box running 11.2.0.1. The 10g database has too many data files scattered within too many file systems. I'd like to consolidate the data files into one or two large chunk in one file systems. Both OSs are RHEL 5. How should I do that using Data Pump Export/Import? I knew there is "Remap" option could be used, but it's only one to one mapping. How can I map multiple old data files into one new data file?

hi
datapump is terribly slow, make sure you have as much memory as possible allocated for Oracle but the bottleneck can be I/O throughput.
Use PARALLEL option, set also these ones:
* DISK_ASYNCH_IO=TRUE
* DB_BLOCK_CHECKING=FALSE
* DB_BLOCK_CHECKSUM=FALSE
set high enough to allow for maximum parallelism:
* PROCESSES
* SESSIONS
* PARALLEL_MAX_SERVERS
more:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28319/dp_perf.htm
that's it, patience welcome ;-)
P.S.
For maximum throughput, do not set PARALLEL to much more than twice the number of CPUs (two workers for each CPU).
Edited by: g777 on 2011-02-02 09:53
P.S.2
breaking news ;-)
I am playing now with storage performance and I turned the option of disk cache (also called write-back cache) to ON (goes at least along with RAID0 and 5 and setting it you don't lose any data on that volume) - and it gave me 1,5 to 2 times speed-up!
Some says there's a risk of lose of more data when outage happens, but there's always such a risk even though you can lose less. Anyway if you can afford it (and with import it's OK, as it ss not a production at that moment) - I recommend to try. Takes 15 minutes, but you can gain 2,5 hours out of 10 of normal importing.

Difference between two dates

Hi
I have two date fields in the ODS..Both are characterists
1. Requested delivery date
2. Actual shipment end date.
I would like to create a calculated KF field for the difference between two dates in a query.
How can I accomplish it?

You have to make Expiration data as nav attribute and create a formula variable then only this date can be used in calculations.
refer this How to...for the same

Getting the difference between 2 dates

Hi,
I am creating a Date object (using today;s day, month and year. hours and minutes come from a config file) and getting the difference between this date and the current date and time.
My code is as follows:
I am passing 07:30 into the method as the parameter aSstart_time.
Calendar newCalendar = Calendar.getInstance(Locale.UK);
    SimpleDateFormat dtformat = new SimpleDateFormat("dd-MM-yy HH:mm");
    int lIYear = newCalendar.get(newCalendar.YEAR);
    int lIMonth = newCalendar.get(newCalendar.MONTH);
    int lIDay = newCalendar.get(newCalendar.DAY_OF_MONTH);
    String lSstartHrs = aSstart_time.substring(0,aSstart_time.indexOf(":"));
    //System.out.println(">>>>>>>>> THE HOURS IS: " + lSstartHrs);
    String lSstartMins = aSstart_time.substring(aSstart_time.indexOf(":")+1,aSstart_time.length());
    //System.out.println(">>>>>>>>> THE MINS IS: " + lSstartMins);
    java.util.Date ldStartTime = new java.util.Date(lIYear,lIMonth,lIDay, Integer.parseInt(lSstartHrs),Integer.parseInt(lSstartMins));
    System.out.println("Year: " + lIYear);
    System.out.println("Month: " + lIMonth);
    System.out.println("Day: " + lIDay);
    System.out.println("Hour: " + Integer.parseInt(lSstartHrs));
    System.out.println("Min: " + Integer.parseInt(lSstartMins));
    System.out.println("The number of milliseconds for current time is: " + newCalendar.getTime().getTime());
    System.out.println("The number of milliseconds for 07:30 is: " + ldStartTime.getTime());
    System.out.println("calendar time: " + dtformat.format(newCalendar.getTime()).toString());
    System.out.println("created time: " + dtformat.format(ldStartTime).toString());
    if(newCalendar.getTime().getTime() < ldStartTime.getTime()){
      System.out.println("The current time is less than the config time (07:30)");
    else{
      System.out.println("The time is greater than 07:30");
    }When I run this program at 10:06am I get the following output:
Year: 2006
Month: 1
Day: 15
Hour: 7
Min: 30
The number of milliseconds for current time is: 1139997962321
The number of milliseconds for 07:30 is: 61098132600000
calendar time: 15-02-06 10:06
created time: 15-02-06 07:30
The current time is less than the config time (07:30)
The Date.gettime() method should measure the number of milliseconds after 01-01-1970 so the number of milliseconds for the current time (10:06am) should be greater than the number of milliseconds for 07:30. A you can see in the above output this is not the case.
Anybody have any idea why this is happening. Am I using the .gettime() method for the correct purpose.
Any ideas or suggestions would be greatly appreciated.
Thanks

It is beacause Calendar use fully defined year as parameter, so Calendar.set(year + 1900, month, date, hrs, min) is (almost) equivalent to new Date(year, month, date, hrs, min)Example:    int year = 85; // old way of specifying a year in a Date
    int month = 3;
    int date = 12;
    int hrs = 12;
    int min = 0;
    Calendar cal = Calendar.getInstance();
    cal.set(year + 1900, month, date, hrs, min);
    Date d = new Date(year, month, date, hrs, min);
    System.out.println(d);
    System.out.println(cal.getTime());You will obtain the same date (except seconds and miliseconds in this case, as they probably won't be zero with Calendar.getInstance(); )

Difference between 2 dates in milliseconds

Hi all,
I need to create a timestamp of difference in milliseconds
between the date and time now and 00:00:00 01/01/1970.
I am currently using:
<cfset timeStamp = dateDiff("s",
createDateTime(1970,01,01,00,00,00), REQUEST.dateTimeNow)*1000>
but that gives me a value of 1.170170719E+012; however I
require a string containing 13 numeric characters.
Any advice appreciated.
Thanks,
Paul

Paul / Adam,
Thank you for your replies.
> The DIFFERENCE between two dates is *not* a timestamp.
It is just a value.
> I presume what you want is the NUMBER of milliseconds
since 0:00 1/1/1970.
Yes, that is true. I am integrating the HSBC card payment
interface and the name of the variable they are requesting is
"timeStamp". I must have just used that as a description of what I
was after rather than just the name.
> "Determines the integer number of units by which date1
is less than date2".
>

will do seconds. And

So <cfset timeStamp = dateDiff("s",
createDateTime(1970,01,01,00,00,00), REQUEST.dateTimeNow)*1000>
should tell me how many seconds there are between 00:00:00 on
01/01/1970 and the current date and time, then the *1000 should
tell me the value in milliseconds?
I have spoken with HSBC and they tell me that the specific
value they are looking for from the timestamp is 13 numerical
characters (e.g. 1170185487375), but the value being returned from
my cfset above is 1.170170719E+012, which includes non numerical
characters.
The HSBC payment server is on a Linux server and my host is
Windows. Are there any differences in the formatting of such a
string?
I cannot see anything I have missed on this.
Any other suggestions?
Thanks,
Paul

Difference between two dates into server behaviors

Good morning all,
I'm trying to create a recordset using server behaviors and as I'm not an expert using php I'm completely lost...
The problem is the following : I want to find into a table all the records where the difference between today date and their creation date (stored in that table of course) is greater than, let's say 30days. How can I indicate that into the variables field ?
Many thanks in advance for your help !

Many thanks !
I was ignoring the DATE_SUB function and it does work in such a simple way… (with a closing parenthesis at the end)
Thanks again !
