DATEADD excluding weekends and holidays

select getdate(),dateadd(day,15,Getdate())
THis gets me today and 15 days from now. However I need 15 business days. I need to exclude weekends and holidays in here so that is looks like this.
where fulldate between getdate() and dateadd(day,15,Getdate())
I have a dim table for dates and have an isholiday = 0 or 1. I just can't figure out how to include this in the DATEADD expression.

Time between dates excluding Weekends and Holidays

I am fairly new to Power Pivot and I am having trouble with this formula. I need my Cycle Time Days column to capture the days between CreatedDataTime and ClosedDateTime excluding Weekends and Holidays. I have a tab that has the holidays but
I can't get the formula correctly?   Jill
CreatdDateTime        ClosedDateTime     Cycle Time Days
12/1/2014                    12/10/2014

first of all you need a separate time table which holds all possible dates for your model
there should be no gaps, it should contain full years and a column of datatype DateTime as unique key
once you have this in place add a calculated column to this table as
=IF(INT(FORMAT([Date], "w")) >= 6, "Weekend", "Workday")
then go back to your original table and add the following calculation for your [Cycle Time Days]-column:
=COUNTROWS(
FILTER(
'Dates',
Dates[Date] >= DateRanges[DateFrom]
&& Dates[Date] <= DateRanges[DateTo]
&& 'Dates'[IsWeekend] = "Workday"
Holidays are a bit more tricky but you can follow the same pattern but you need to get the holidays from somewhere

Working day formula that excludes weekends and holidays in WEBI

Hi Guys,
Can we calculate a working day formula that excludes weekends and holidays in WEBI OR in Universe?
The universe I am working on is using stored procedures, so there are no joins or modelling done. Although there is a workday stored proc that I can bring in the universe.
I am just thinking if there is no modelling or joins done in the universe how will this help me in webi?
Your suggestions will be very helpful.
Thanks,
Jitan

One more suggestion I need from you -
I have a Work_Calendar_VW that has the following columns -
Calendar_Date - 5/1/2014
Calendar_Year - 2014
Calendar_Month - 5
Calendar_Day - 1
Work_Day - 1
Day_Type - WD (Work Day) For Weekends this will be displayed as WE
The columns have all dates for current year in SQL Server.
I am going to pull this into the universe and create 2 derived tables to calculate MTD Day counts.
Derived Table 1 - Calculate Yest Work Day... this will remove all the weekends and holidays and give me the last working day. This includes couple of case statments to check each day if it's a working day or weekend.
For Work Day the above code will be 1 and for weekend 0
Derived Table 2 - This will give me the count of working days in current month using the above view and Derived table 1 Below is the code -
SELECT COUNT(*)
FROM Work_Calendar_VW
WHERE [Work_Day] = 1 AND
(Calendar_Date BETWEEN CAST(CONVERT(VARCHAR(25),MONTH(LastWoringkday()),101) + '/01/'
+ CONVERT(VARCHAR(25),YEAR(LastWoringkday()),101) AS DATE)
AND LastWoringkday()).
I cannot do joins because this universe has been built using stored proc and would like to implement this in BO universe.
let me know if this is the right approach.
Thanks,
Jitan

Add working days to a date excluding weekends and holidays

Hi there,
I need to write a function that will take a specified date and number of days to add as input parameters, and return the working day based on the number of days to add parameter, excluding weekends and any holidays held in a holiday table.
Here is my function so far -
CREATE OR REPLACE FUNCTION f_add_work_days(pd_date IN DATE
,pn_add_days IN PLS_INTEGER) RETURN DATE IS
pd_in_date DATE := pd_date;
ld_next_holiday DATE;
ln_days_left PLS_INTEGER := pn_add_days;
CURSOR cu_holiday(pn_date IN ge740.holdte%TYPE) IS
SELECT pck_utility.f_dtcnv(g.holdte)
FROM ge740 g
WHERE g.holdte >= pn_date
AND g.maint <> 'D'
ORDER BY g.holdte ASC;
BEGIN
OPEN cu_holiday(pck_utility.f_dtcnv(pd_in_date));
FETCH cu_holiday
INTO ld_next_holiday;
CLOSE cu_holiday;
LOOP
IF ln_days_left = 0 THEN
EXIT;
END IF;
pd_in_date := pd_in_date + 1;
IF pd_in_date > ld_next_holiday THEN
OPEN cu_holiday(pck_utility.f_dtcnv(pd_in_date));
FETCH cu_holiday
INTO ld_next_holiday;
CLOSE cu_holiday;
END IF;
CASE
WHEN TO_CHAR(pd_in_date
,'fmDAY') = 'SATURDAY' THEN
pd_in_date := pd_in_date + 2;
ln_days_left := ln_days_left - 1;
WHEN TO_CHAR(pd_in_date
,'fmDAY') = 'SUNDAY' THEN
pd_in_date := pd_in_date + 1;
ln_days_left := ln_days_left - 1;
WHEN pd_in_date = ld_next_holiday THEN
pd_in_date := pd_in_date + 1;
ln_days_left := ln_days_left - 1;
ELSE
ln_days_left := ln_days_left - 1;
END CASE;
END LOOP;
RETURN(pd_in_date);
END f_add_work_days;
I think there is something wrong/missing in the logic as I can't get it to cater for say a double bank holiday(25/26th Dec - if the input parameters are 24/12/2007 and 2, which should return the 28th but returns the 26th!!).
I'm relatively new to PL/SQL and Oracle, so any help, advice, ideas would be greatly appreciated!
thanks in advance

Calculate the Difference Between two dates excluding weekends and Holidays

Hi,
We need to calculate the difference between the two dates by excluding the Local public holidays (It is global and varies across countries) and weekends should not be included in calculation for a business day in OBIEE.
We have two dates: Open date and close date when ever close date is null we are calculating age based on taking the current timestamp and need to exclude the weekends and Holidays when ever the close date is null.
Ex:
Col1 col2 Total
11/9/2010 2:46:38 PM Null 13
11/2/2010 8:06:26 PM 11/3/2010 5:37:03 PM 1
(In the Total we shouldn't include the weekends,holidays)
Please let me know how to calculate the difference between two dates by excluding the weekends and holidays.
Thanks

Payment term with fixed day but exclude weekends and holidays

Hello,
our customer has a requirement to have payment term that is like this:
Due date: fixed day 15th next month.
If due date falls in weekend or holiday due date will move to next business (working) day.
We have working payment term which is always the 15th on next month but it falls to weekends.
I was searching SDN found something but not working.
Could you please send me a step-by-step configuration how to exclude the weekends and holidays?
Thank you a lot.
Best regards,
Lubos

Dear Lubos,
unfortunately waht You need to have It is impossible into the SAP Standard System.
Please be aware that the vendor invoice has two relevant dates:
Baseline date   > INVFO-ZFBDT
Due on   > INVFO-NETDF
The Baseline date is managed by the "Term of payment", transaction obb8, frame
"Baseline date calculation" where You can put for example :
Fixed day            30
Additional months     3
This means that if You put as Document date 01.01.2009, the baseline date
will be 30.04.2009 (fixed day 30, additional months 3).
The "Due on" date will start ALWAYS from "the Baseline date"
(that in my example is 30.04.2009) and according to the below
"Term of payment" , the System will add
31 days, so the Due on date will be 31.05.2009.
Term      Percentage   No. of days / Fixed date Additional months
1.               %      31
2.               %
3.
You could think to use the FI substitution to reach Your goal.

Hello All
I have one requirement here, where delivery dates should propose only working days and it should not allow to add weekends and holidays during the creation of sales order.
I would like to know if there are any standard settings to be done in plant or shiping point?
Kindly need all your input on this
Thanks

Hello All
Same calendar has already been assigned in shipping point,plant and sales org and also in the calendar holidays been maintained, even though when we create a sales order it will accept weekends and holidays

Exclude Weekends and Holidays while applying for leave...

Hi,
Could anyone help me out in excluding holidays while applying for leave via absence management (employee self service) in R12? While clicking on calculate duration it includes weekends as well by default. Since updating the formula BG_ABSENCE_DURATION will involve creating UDTs, modify UDF and additional effort; I tried creating workschedulle and updated the profile HR: Schedule Based Absence Calculation to 'Yes' following the metalink note 'Schedule Based Absence Calculation in Self Service' [ID 437083.1] but no luck. Is there any other additional setup that needs to be done or its better to update Fast Formula. Kindly advise on the same. Thanks in Advance!!!
Thanks,
Ahmed

Thanks much Gaurav. I was able to work it out by creating work schedule itself. I reckon I missed out selecting the schedule pattern. We need to ensure that after creating schedule the pattern needs to be selected and launched. After a while it gets effected in the system. Just in case if others are trying to implement work schedule for working days between Saturday to Wednesday following are the step involved. I have created two schedule pattern with day start as 1 and day stop as 4; and another pattern with day start as 7 and day stop as 7. It works like charm....:)

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules (you do not). Temporal
data should use ISO-8601 formats (you do not!). Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
We hate functions in SQL. This is a declarative language and you are using it like 1950's FORTRAN. We hate local variables (more FORTRAN!)
The name of a function has to be either a known, common name, like “sine”, “cosine” etc. Or it is “<verb>_<object>”; you think a noun is a verb! Do you really need BIGINT? Why did you invite garbage data with it? Why do you think that SQL
uses AM/PM? Have you never seen the TIME data type?
Think about “date_val” as a data element name. A date is a unit of temporal measurement on a calendar scale. This would be a “<something>_date” in a valid schema.
>> Is there a way to get this to work as a function? <<
Probably, but why do it wrong?
Build a calendar table with one column for the calendar data and other columns to show whatever your business needs in the way of temporal information. Do not try to calculate holidays in SQL -- Easter alone requires too much math.
The julian_business_nbr is how SQL people do this. Here is the skeleton.
CREATE TABLE Calendar
(cal_date DATE NOT NULL PRIMARY KEY,
julian_business_nbr INTEGER NOT NULL,
Here is how it works:
INSERT INTO Calendar
VALUES ('2007-04-05', 42),
('2007-04-06', 43), -- Good Friday
('2007-04-07', 43),
('2007-04-08', 43), -- Easter Sunday
('2007-04-09', 44),
('2007-04-10', 45); --Tuesday
To compute the business days from Thursday of this sample week to next Tuesday:
SELECT (C2.julian_business_nbr - C1.julian_business_nbr)
FROM Calendar AS C1, Calendar AS C2
WHERE C1.cal_date = '2007-04-05',
AND C2.cal_date = '2007-04-10';
See how simple it can be when you stop trying to write FORTRAN and think in sets?

Calculating number of days without weekend and holidays

Hallo all,
can someone help me with a formular to calculate the number of days with Crystal Reports 2008 between two dates without weekends and holidays
eg.
date one = 03/24/2010
date two = 03/29/2010
Result should be 4 days as 03/27 and 03/28 will be a weekend.
Plus how to exclude holidays ?
Thank you very much
Gerald

As Doug mentioned, Holidays are very location specific, and are you talking about "corporate holidays" where the company is closed, or "public holidays" where banks (<g>) are closed?
I'd suggest setting up a calendar table (if you don't have one already), one record per date. You could make it work-days only, days-off only, or all dates with a flag to indicate if it is a work date. You could then use that to count the number of work days. By using a table, you wouldn't have to change any code to (a) extend your calendar to the following year, or (b) change holiday dates if the holidays change. (I'm thinking corporate holidays, where the company might be closed Friday 12/24/10 in observation of Christmas, but would usually only close on the 25th.)

If you can't add the previous_business_date to your holiday table, then it gets slightly more complicated (because you have to skip back through consecutive holidays AND weekends AND any more consecutive holidays - ie in UK you'd have to skip back through Easter Monday, the Easter Weekend and Good Friday - last busines day is what we call Maundy Thursday.

Time Passage Calculation excluding Weekends and Non-work hours

Good Afternoon Everyone!
I am currently using the expression below to determine the amount of time that has passed since a Task has been created.
TIMESTAMPDIFF(SQL_TSI_MINUTE, Activity."Created Date", NOW())
We have a completion goal for a specific task type of 2 hours (120 minutes), but it should only be calculated minutes between 7 AM and 4 PM and only on week days.
So, a task created at 3:50 PM on a Friday that is completed at 7:30 AM on the following Monday should only calculate to 40 minutes of time.
I am at a loss for where to start tackling this problem. If any of you can help I would be very appreciative!

Hey Paul, thanks for the prompt. I see now that the formula is incomplete.
As I have just taken the difference in days between the Activity Start Time and End Time, it will consider any weekend. But its incomplete as it considers only 15 hours of a day and not the remaining 9 hours for weekends. For holidays - we do need a field or something to identify it like Activity Type = 'holiday'.
So the ELSE* part of revised formula would be something like this:
... ELSE TIMESTAMPDIFF(SQL_TSI_MIN,activity start time,activity end time) - (60*15*(DAY(Activity End Time) - DAY(Activity Start Time))) - (60*9*(COUNT(DISTINCT CASE WHEN DAYOFWEEEK(Date.Date) IN (6,7) OR ~some field to identify holiday~ = 'something' THEN 1 END)) END
now imagine there's one activity that started on Friday 7:00 AM and ends on coming Monday at 4:00 PM.
Actual duration is 18 hours.
Now,the first term after ELSE will give 81*60 minutes. next term should give 45*60 minutes. third term would be 18*60 min.
so the entire expression would return 18 hours.
Even if there's a holiday, then i guess the 'OR' part should capture it.
I hope this makes sense. Please let me know if it should need any further corrections.

Fucntion to Calculate business days (exclude weekends & holidays) between two days

Hello,
I need to be able to calculate business days between two dates excluding weekends and holidays. I do have a date dimension and also flags which denote weekday, holiday. Would really appreciate help in building a udf for the business days calculation.

SLA Calculation needed to exclude Holidays, Weekends and Off business hours

Hello all,
I am to create a function that will calculate the minutes between two dates for company work hours, excluding the weekends.
The function here from RSingh() is ideal for this purpose; however I am now asked to excluded company holidays also.
http://social.msdn.microsoft.com/Forums/sqlserver/en-US/de4f7661-c702-4a10-ad06-3e28e4e0a83c/sla-calculation-help-needed-in-excluding-weekends-and-off-business-hours-for-calculation?forum=transactsql
With a table called 'holidays' that contains holiday dates. I would hope to modify the function to exclude these.
Please, how can this be accomplished?

My approach would be something like this
Populate a calendar table that includes a work start and work end time for each day (none for weekends and holidays)
SELECT *
INTO #cal
FROM (
   SELECT CAST('20140117' AS DATE) AS CalendarDate
       , CAST('20140117 09:00' AS DATETIME) WorkStart
       , CAST('20140117 17:00' AS DATETIME) AS WorkEnd
   UNION ALL
   SELECT CAST('20140118' AS DATE) AS CalendarDate
       , CAST(NULL AS DATETIME) WorkStart
       , CAST(NULL AS TIME) AS WorkEnd
   UNION ALL
   SELECT CAST('20140119' AS DATE) AS CalendarDate
       , CAST('20140119 09:00' AS DATETIME) WorkStart
       , CAST('20140119 17:00' AS DATETIME) AS WorkEnd
   UNION ALL
   SELECT CAST('20140120' AS DATE) AS CalendarDate
       , CAST(NULL AS DATETIME) WorkStart
       , CAST(NULL AS TIME) AS WorkEnd
   UNION ALL
   SELECT CAST('20140121' AS DATE) AS CalendarDate
       , CAST(NULL AS DATETIME) WorkStart
       , CAST(NULL AS TIME) AS WorkEnd
   UNION ALL
   SELECT CAST('20140122' AS DATE) AS CalendarDate
       , CAST('20140122 09:00' AS DATETIME) WorkStart
       , CAST('20140122 17:00' AS DATETIME) AS WorkEnd
   ) X
Use a query something like the following to work out the number of minutes
DECLARE @Start DATETIME = '20140117 13:00'
DECLARE @End DATETIME = '20140122 17:00'
SELECT SUM(diff)
FROM (
SELECT DATEDIFF(MINUTE, CASE WHEN CAST(@Start AS DATE) = CalendarDate
AND @Start > WorkStart THEN @Start ELSE WorkStart END, CASE WHEN CAST(@End AS DATE) = CalendarDate
AND @End < WorkEnd THEN @End ELSE WorkEnd END) AS diff
FROM #cal
WHERE CalendarDate BETWEEN CAST(@Start AS DATE)
AND CAST(@End AS DATE)
) X
Edit: Totally mucked up the example calendar table so I've changed it

Regarding Weekend Dates and Holiday Dates - answer please

Hi have
Sales order date and amount sold columns in my report.
The user requirement is they want to see all the sales that are done during the weekend and Holidays but the report should only show the
sales order date and the amount (the weekend and holiday sale amount should roll up to the next business day total)
lets say there was a sale on March 16th for $100, March 17th for $100 and for March 18th there is a sale of $100 the March 18th Sales amount should be $300 in the sales amount per day column.
The orders are taken daily including the holidays and weekends and in the EBS 11 the source system the ordered date is the date the order was taken.
In obiee 10g the reports and queries are showing all the orders that are placed on the actual day, does not matter its a holiday or weekend.
the users does not want to see the weekend dates and holidays but they want the amount to be rolled up.
How to convince the user that there is no capability in OBIEE 10g we cant get the orders by the calendar date.
is there a function in obiee to roll up the weekend and holiday sales amount?
They way Iam approaching this is
imported the BOM_Calendar_date from EBS and doing the mappings in OWB(their ETL tool) filtering by the country USA
and thinking about writing a function to roll the amount where the weekend holiday column is "NULL"
if any one has any other idea please let me know.
TIA

How does day dim know about holidays? based on client or enterprise calendar you need to let know day dim!.
You might have to customize day dim or else create custom table for holidays with date_wid as Jul 4 is holiday for this 20130704 is the key for that holiday and join this to day dim.
Hope this helps, if does mark

DATEADD excluding weekends and holidays
