Date difference calculation help needed

Hi,
I have a form with a date field and one text field which is hidden..in case the date field value is less than the current date minus 3 years then the text field should display else not. Please advice what logic/code can be used.
Any suggestions would be highly appreciated !!
Thanks

In the mean time, a couple of stylisitc suggestions:
if(start.getTime().before(end.getTime()) == true)
// == true is redundant and cluttersome
if(start.getTime().before(end.getTime()))
Long L = new Long(diff);
return L.intValue();I'd suggest returning a long, rather than an int. If you insist on returning an int, because you're sure that the number of days will never be more than Integer.MAX_VALUE, then add an assertion that its not.
assert diff <= Integer.MAX_VALUE : diff + " too big";The Long is overkill. If you do have a small enough value, just do return (int)diff;

Date difference calculation - help!

hey people, i've got the below method, i'm trying to calculate the difference between two dates. the calculation is wrong as it is outputing the wrong duration... can anyone help?
public int getDuration(Date startDate,Date endDate)
GregorianCalendar start = new GregorianCalendar();
start.setTime(startDate);
GregorianCalendar end = new GregorianCalendar();
start.setTime(endDate);
long diff = 0L;
if(start.getTime().before(end.getTime()) == true)
diff = end.getTimeInMillis() - start.getTimeInMillis();
diff = diff/(24*60*60*1000);

Date difference calculation

Hello Everyone,
We need to calculate a day difference between two days. There is many suggestions about using the following approach:
(date1.getTime() - date2.getTime())/86400000.
This seems to work until we hit a Daylight Savings Time issue and nobody seems to talk about that. When in April, for example, we get 1 hour less then the result of the calculation above will not be the whole number. Well, we can use Math.ceil() function for that. Then, in October, we get 1 hour back so now we have to use Math.floor() function to get the right result.
Does anybody have any idea as to when to use one or another. I was thinking of using modulus division. If the result is not equal to zero then we have to apply one of those functions. The question now is, how to identify which function to apply? Or is there any other, less cumbersome way to properly get day difference between two dates?
Any help will be greatly appreciated.
Thanks,
Yourii

I think i figured out how to calculate the difference in days with Daylight Savings Time changes. Here is the code:
     * This method returns difference in days between two Dates passed in.
     * It identifies Daylight Savings Time changes and automatically
     * adds or substracts one hour when needed ...
     private int dayDifference(java.util.Date date1, java.util.Date date2) {
     final long M_SECS_PER_DAY = 24*60*60*1000;
     final long M_SECS_PER_HOUR = 60*60*1000;
     long days = (date1.getTime() - date2.getTime());
     if (days%M_SECS_PER_DAY != 0) {
     if ((days + M_SECS_PER_HOUR)%M_SECS_PER_DAY == 0) {
     System.out.println("Adding one hour ...");
     days += M_SECS_PER_HOUR;
     } else {
     System.out.println("Substracting one hour ...");
     days -= M_SECS_PER_HOUR;
     } else {
     System.out.println("No alterations made ...");
     return (int)(days / M_SECS_PER_DAY);
Let me know what you think ...

Date Difference Calculation in BW3.5

Hi
We are calculating date differences between 2 dates i.e. Delivery Date - System Date.For System date we used variable exit to derive the value.But when we create CKF on Delivery Date,we necessary have to keep date field in Drilldown(in rows).But reports needs to give Overview while including date field in rows removes the granularity.
Is thier any other way we can handle this situation.
Regards

You have to put ur delivery date in Rows if u r doing the Formula variable with replacement path. There is no option.

Hi,
I always find a post by John Booth's a useful guidance when you are wanting to run calculations with dates, have a read at :- Calculations with dates
If you are using Version 11 you also have a look at the new date functions e.g. @DATEDIFF - http://download.oracle.com/docs/cd/E12825_01/epm.111/esb_techref/calc_datediff.htm

Calculations Help Needed

Here is the situation:
I am doing a quick "play around" between Pages/Word, Numbers/Excel and Keynote/Powerpoint.
This is to refresh my memory to windows, since I am going into a short-term (5 - 7 or 8 years) of IT.
I need help with calculating the average time of sunrise for one week, using two sheets.
The times given are 5:40am, 5:41am, ........ 5:46am. The cells: B5 - B11 (Sunrise Column for week 1). The name for this sheet is "Weekly".
The equation is going to be place in cell B5 of sheet named "Monthly" representing the average time of sunrise for that week.
In excell, I understand "Weekly!B3" refers to cell B3 on worksheet "Weekly".
How would I do this in numbers? (I will figure out how to do it in Excell.)
Thanks again guys (and ladies)!

In fact, the problem is not the one which you described.
The way to reference a cell or a range of cell is perfectly described in iWork Formula and Functions User Guide in which every user may get it.
The important thing to know is that in NumbersLand, 5:40am isn't a time value but a date_time one.
In the tables above, I deliberately choose to insert time values entered at different dates so, the formula inserted in Monthly :: B5
=AVERAGE(Weekly :: B5:B11)
return an exact result which doesn't match what we are wanting to get.
This is why I used the auxiliary column C
In Weekly :: C5, the formula is :
=TIMEVALUE(B)
Apply Fill Down to insert the formula in rows below.
The formula returns the time value using the unit day.
In Monthly // C5, the formula is :
=AVERAGE(Weekly :: C5:C11)
but I guess that you don't wish to get the result in this format.
In Monthly // D5, the formula is :
=DURATION(0,AVERAGE(Weekly :: C5:C11))
You may edit the format of this duration cell as you want.
An alternate formula would be :
=TIME(,AVERAGE(Weekly :: C5:C11)*24*60,)
But CAUTION, one more time, as you may see, the cell will contain a date component.

Application Server Data Source settings help needed (10.1.2.0.2)

Hi,
Can someone tell me what maximum values can I set in the following properties under Connection Attributes when I define a DataSource on
Application Server. I have almost 25+ web application deployed on my 10.1.2.0.2 server that all uses one data source I have defined. Now the issue is the number of requests
are very high and every now and then I get timeout error when trying to get the database connection. At one particular instance at peak time I may get over 200+ requests that
do some databse connections etc. Following are my current settings. But need to increase some more but wondering what are the maximum values I can have. I have only one server 10.1.2.0.2
Connection Retry Interval (seconds) = 5
Max Connection Attempts = 3
Cached Connection Inactivity Timeout (seconds) = 30
Maximum Open Connections = 60
Minimum Open Connections = 10
Wait For Free Connection Timeout (seconds) = 15
What other properties can I have to make use of datasource effectively.
Thanks

PDF form field calculation help needed

I need to make some simple calculations on a pdf form and need some help.
I have a form field for number of guests.
A field for a set cost for various tickets (there are 3 levels of ticket prices) (I might not need this field).
A subtotal of the guests attending and ticket price.
A grand total of the subtotals.
I can't figure out how to either put in a fixed cost in a form field or input a calculation so that the number of tickets is muliplied by a fixed number and gives me a subtotal.
Thanks.

Ok. I finally got the calculations to work. But..... when I save and open in Reader, they don't work. Go back to Pro, they don't work there now either. They also don't show up under the Set Field Order Calculations. To reset them, i have to erase the calculations, save, redo the calculations. Preview the form and everything works — calculations happen and i get a total.
Adobe Reader usage rights are enabled.
Why is this so hard?
I found this thread http://forums.adobe.com/message/1152890#1152890 about it. Is this bug still going on since 2009?
Ok. Apparently you have to enable reader rights after the form is done. It seems to work now. What a pain.

Date difference calculation with user input variable

Hi,
I have the following requirement in BEx:
The user inputs a date value and I have to calculate the difference between the date entered by the user with the Due Date in the cube, to determine the number of backlog days. Basically, I need to calculate Past Due in number of days. I need to display the Amount due for the Time buckets like 1 -10 days, 11 -30 days.
The report output has to be in the format below:
Columns:
1 u2013 10 days Past Due      $100.00
11 u2013 30 days Past Due    $15.00
Rows:
Customer#
The cube has data from Jan 2005 to June 2008.
For Eg:   User Input Date =   04/30/2008.
It should compare the input date to the due date for each record in the cube.
Any suggestions are appreciated.

Hi Kumar,
We have developed simar reports in our previous projects.
You need to follow the following steps.
1. Create a new restricted key figure globally on Past Due $100. Restriction details I will let you know in the ensuing steps.
2. Create another restricted key figure globally on Past Due $15. Restriction details I will let you know in the ensuing steps.
3. Create a Z varuable on Calday and offset it -1 (use the button next to exclude button).
4.Create another Z varuable on Calday and offset it -10 (use the button next to exclude button).
5. Create another Z varuable on Calday and offset it -11 (use the button next to exclude button).
6. Create another Z varuable on Calday and offset it -30(use the button next to exclude button).
7 Restrict the RKF past due 100$ (defined in sl 1)between the variable range defined in 3 and 4.
8. Restrict the RKF past due 15$ (defined in sl 2) between the variable range defined in 5 and 6
Now drag and drop those two RKF to column and you will get the desired result in C1 and C2 as follows:
Columns:
C1 :1 u2013 10 days Past Due $100.00
C2 :11 u2013 30 days Past Due $15.00
If the above info serves your purpose, please reward me with the point.

Subha

Very simple calculation help needed.

I am a non-techie person being tasked with creating a form. Java? Thats coffee right?
see what I mean .
Anyway I need to have a form calculate the difference between two dollar amounts.
They are: Previous Check Amount ____________
Current Check Amount __________
Difference(+/-) _____________
I looked at doing the calculation via the value field on the calculate tab. But I see I cannot do that unless I choose the Custom Calculation Script and writing it myself. I am not sure how to do that. If I could send cookies to my savior I would.
Thanks!!

Gilad,
Thanks for the reply,
The fields are "Previous Check Amount" and "Current Check Amount" and I need to calculate whatever (+/-) difference there would be between the two......

Date Difference Calculation problem

I am creating a form which should calculate the number of days between two calender dat
es using the Date2Sum expression but my result cell gives me
zeo despite setting the locale and the calculation correcttly. Where could
my problem be?
Darlington Sakwa

Validate the date patterns on the date fields match the date patterns used in Date2Num. For example, the attached has a start date with the display date pattern date{YYYY-MM-DD} and that matches the date pattern in my Date2Num function call.
// form1.page1.startDateNum::calculate - (FormCalc, client)
if (form1.page1.startDate.isNull) then
$.rawValue = ""
else
$.rawValue = Date2Num(form1.page1.startDate.rawValue,"YYYY-MM-DD")

Data Load scenario- help needed

Hi gurus,
Please help me with the below scenarios for the LO mechanism:
Rec 1 entered in R3 between T1 and T2 (during R3 setup table population). When does Rec1 get into BW?
Rec 2 entered in R3 between T2 and T3 (after setup table population but before initialization loads). When does Rec 2 get into BW?
Rec 3 entered in R3 between T3 and T4 (during initial loads in BW). When does Rec 3 get into BW?
Rec 4 entered in R3 after initialization is completed after T4. When does Rec 4 get into BW?
Time
T1                                          T2    T3                                                                               T4
|--|---||--
       Rec 1                                Rec2                                   Rec 3                                                   Rec 4
T1 T2 Setup Tables populated
T3 T4 Initial Loads performed
T4 onwards Delta Loads performed

Hi ,
senario1;Rec 1 entered in R3 between T1 and T2 (during R3 setup table population). When does Rec1 get into BW?
during the setup table filling ,v3 jobs will be descheduled
you need to lock all the user's (no user can post documents)
Rec 2 entered in R3 between T2 and T3 (after setup table population but before initialization loads). When does Rec 2 get into BW?
here just setup table is filled,however init is not performed
so still v3 jobs will be in descheduled mode ,the posting which were/are happened sits in application tables
Rec 3 entered in R3 between T3 and T4 (during initial loads in BW). When does Rec 3 get into BW
here init is running,it will be down time for R/3 due to heavy load processing to BW
so still v3 jobs will be in descheduled mode ,the posting which were/are happened still sits in application tables
Rec 4 entered in R3 after initialization is completed after T4. When does Rec 4 get into BW?
after init,now we need to schedule v3 jobs, so all the postings(which were posted earlier/which are posted for the moment) now will transfer from application tables to delta que depending on the update mode(direct/queued/un serialized)
Hope this helps you!!!!!!!

ALE Data Transfer - Urgent help needed

I am trying to set up an ALE interface from a SAP ECC 6 system to another SAP ECC 6 system using HRMD_A idocs. The complication I have is in the receiving system, I need to generate a new PERNR for all employees transferred.
Can anybody advise how to go about doing this?
Many thanks
Jez

Hi you can send the employees from sender system to reciever system.
With the help of transaction pfal you can send the personnel number.
You have to choose the ploan version 01
object type will be p
in object id write the employee number which will be transferred to the reciever system
Then push the run button.
But you have to configure HRMD_A in ALE implementation.
