Aggr in pivot table

Fri, 20 Nov 2009 17:49:34 GMT

Dear community,

since some time I am trying to solve a problem from the logistic sector with a dynamic dimension in a pivot table.

I would like to know how often (for example) "5 events at the same time" have been the "maximum number of events at the same time" between 9am to 10am.

Therefor I have created a calender with every minute from the start to the end date what allows me to count the number of events at the same minute. With this I am able to sort out the max. number of events at the same time by hour.

So far so good - but now I'd like to have table that counts the number of maximum events per hour which happen during a certain period.

Please find attached file with more information regarding this problem.

Maybe the solution is very simple or maybe impossible.

Anyway, I am thankful for every comment.

Cheers,

Nico

Hmm, seems to me that no one has an idea yet?

Me neither.

Hi,

The following Expression will give you max number of concurrent events occuring per minute in an hour:

Max(Aggr(Count(ID),MinutenkalenderDate,HourkalenderDate,Date))

If you keep the Date and Hour as Dimensions, this should give you the max concurrency for the hour.

Here is the sample data generated:

HourkalenderDate	=Max(Aggr(Count(ID),MinutenkalenderDate,HourkalenderDate,Date))
	18
00:00 - 01:00	8
01:00 - 02:00	7
02:00 - 03:00	6
03:00 - 04:00	6
04:00 - 05:00	6
05:00 - 06:00	7
06:00 - 07:00	7
07:00 - 08:00	7
08:00 - 09:00	10
09:00 - 10:00	14
10:00 - 11:00	14
11:00 - 12:00	16
12:00 - 13:00	16
13:00 - 14:00	15
14:00 - 15:00	18
15:00 - 16:00	14
16:00 - 17:00	15
17:00 - 18:00	13
18:00 - 19:00	14
19:00 - 20:00	15
20:00 - 21:00	17
21:00 - 22:00	11
22:00 - 23:00	10
23:00 - 00:00	9

Hi Vidyut,

thanks for your quick reply. Unfortunately this is not the solution I am looking for.

As mentioned before, I'd like to generate a table with the following dimensions - "HourkalenderDate" (static) and "Max. Number of Events" (dynamic) (see the file in the first contribution) - and the information should represent an aggregated value with respect to the following question:
How many times between - let's say - 14pm -15pm and during a given period (16 days) the "Max. Number of Events" was 1 or 2 or 3 or 4 or 5 or 6 or 7 or ... ?
Since there are just 16 values (one for each day) the sum of values must be 16 for every hour.

Example:

max. no. of events 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

"13:00 - 14:00" 2 4 2 2 1 2 1 0 1 0 0 1 0 0 0 0 0 0 0 = 16

"14:00 - 15:00" 1 3 2 2 0 0 1 0 1 0 2 0 1 2 0 0 0 0 1 = 16

Behind "1" for "14:00 - 15:00" and "8 events" stands a formula what considers that on just one of the 16 days the maximum number of events at the same time (by looking at the minutes), from 14pm- 15pm, was 8.

Maybe there is a work around?!
