Network Days

Wed, 22 Aug 2012 09:40:15 GMT

Hi,

I have an Opened Date and a Closed Date. I need the exact difference between the two excluding Weekends and Holidays in num format.

Using N/w days gives me value in whole numbers.

Eg:

Open Date	Closed date	Diff
8/9/12 11:08 AM	8/9/12 2:57 PM	0.16

Regards.

You can try something like this:

Set TimestampFormat = 'M/D/YY hh:mm TT';

LOAD *,

num(interval(

NetWorkDays(DT1+1,DT2-1)

if(NetWorkDays(DT2,DT2),frac(DT2)+(floor(DT1)<>floor(DT2))*-1,1)

-if(NetWorkDays(DT1,DT1),frac(DT1),1)

)

)) as Diff;

LOAD * INLINE [

DT1, DT2

8/9/12 11:08 AM,8/9/12 2:57 PM

8/18/12 09:20 AM,8/20/12 01:13 PM

8/17/12 09:20 AM,8/20/12 01:13 PM

8/17/12 09:20 AM,8/19/12 01:13 PM

];

You'll need to add your list of holidays to each single Networkdays() function as third argument (check the Help for more details).

Thanks Stefan.. But the values are one day lesser... The correct value has to be 2.94, but gives 1.94...

Secondly,

if(NetWorkDays(DT2,DT2),frac(DT2)+(floor(DT1)<>floor(DT2))*-1,1)

-if(NetWorkDays(DT1,DT1),frac(DT1),1)

)

should i be adding the holiday list like below in the other 2 n/w days after defining a variable fr holidays.

if(NetWorkDays(DT2,DT2),frac(DT2)+(floor(DT1)<>floor(DT2))*-1,1,$(vhol))

-if(NetWorkDays(DT1,DT1),frac(DT1),1,$(vhol))

)

The correct value for which pair of timestamp values?

Secondly,
if(NetWorkDays(DT2,DT2),frac(DT2)+(floor(DT1)<>floor(DT2))*-1,1)
-if(NetWorkDays(DT1,DT1),frac(DT1),1)
)
should i be adding the holiday list like below in the other 2 n/w days after defining a variable fr holidays.
if(NetWorkDays(DT2,DT2),frac(DT2)+(floor(DT1)<>floor(DT2))*-1,1,$(vhol))
-if(NetWorkDays(DT1,DT1),frac(DT1),1,$(vhol))
)

You need to add the variable as argument to the NetworkDays function, not to the if() statement.

Eg:

I do get 7.16 and 4.98 with the code I posted above. Could you double check your script? Or post the code snippet you're using?

Re: Network Days

Thank you.. It works fine..

Using the same n/w days, i also need to calculate the difference b/w 2 dates excluding sundays for RegionA and excluding Mondays for RegionB and of course national holidays as well as holidays based on regions. any ideas?

Regards.

Any ideas on atleast difference between two days exclusing only Sundays and Holidays??

Re: Network Days

Networkdays function will always exclude saturday and sundays.

If your holidays are never on a saturday, you can maybe modify above code to check the weekday for the begin and end date and add the number of saturdays inbetween. But I believe you could have saturdays as holiday, right?

You can also create a calendar with all sundays and holidays flagged. Then... Hm, probably needs a rather complex script to check the calendar for each date in your interval.

Or browse the internet and search for a VBScript or JavaScript function that might help you. I am pretty sure you should be able to find something.

For example, this looks quite promising (for a start):

You can create a QV macro code from this and call the functions in the script, just like QV functions.

Just some ideas.

Another idea:

Set TimestampFormat = 'M/D/YY hh:mm TT';

Set vHol = '41130,41140';

INPUT:

LOAD *, recno() as ID INLINE [

DT1, DT2

8/9/12 11:08 AM,8/9/12 2:57 PM

8/18/12 09:20 AM,8/20/12 01:13 PM

8/17/12 09:20 AM,8/20/12 01:13 PM

8/17/12 09:20 AM,8/19/12 01:13 PM

6/27/12 12:41 PM, 7/6/12 4:38 PM

6/29/12 4:45 PM, 7/6/12 4:19 PM

];

TMP:

LOAD ID,

daystart(DT1)+iterno()-1 as Date,

if(iterno()=1, frac(DT1), 0) as Start,

if(daystart(DT1)+iterno()-1=daystart(DT2), frac(DT2),1) as End

Resident INPUT

while daystart(DT2) >= daystart(DT1)+iterno()-1;

left join (INPUT) LOAD

ID,

sum(End-Start) as Duration

Resident TMP where WeekDay(Date)<6 and not match(Date,$(vHol)) group by ID;

drop table TMP;

in above where clause, you can set your requirements. If you want to exclude sat and sun, use where Weekday(Date)<5. I put in some few fake holidays in variable $(vHol), but you can build the variable also from a holiday table, there are some samples here in the forum on how to do this.

Hi Stefan,

What is we have 10 hrs as working for weekday and 4hrs working for sat. we have to exclude sunday and holidays.

How can we modify the below code:

INPUT:

LOAD *, recno() as ID INLINE [

DT1, DT2

8/9/12 11:08 AM,8/9/12 2:57 PM

8/18/12 09:20 AM,8/20/12 01:13 PM

8/17/12 09:20 AM,8/20/12 01:13 PM

8/17/12 09:20 AM,8/19/12 01:13 PM

6/27/12 12:41 PM,7/6/12 4:38 PM

6/29/12 4:45 PM, 7/6/12 4:19 PM

8/1/12 09:00 AM, 8/3/12 10:00 AM

8/3/12 03:00 PM, 8/6/12 09:00 AM

];

TMP:

LOAD ID,

daystart(DT1)+iterno()-1 as Date,

if(iterno()=1, rangemin(rangemax(frac(DT1),maketime(8)),maketime(18)), maketime(8)) as Start,

if(daystart(DT1)+iterno()-1=daystart(DT2), rangemax(maketime(8),rangemin(frac(DT2),maketime(18))),Maketime(18)) as End

Resident INPUT

while daystart(DT2) >= daystart(DT1)+iterno()-1;

left join (INPUT)

LOAD

ID,

interval(sum(End-Start)) as Duration

Resident TMP where WeekDay(Date)<5 and not match(Date,$(vHol)) group by ID;
