Extract Data Having # or Sum more than certain threshold, within certain Time Range.

feira_feira — Thu, 12 Mar 2015 10:30:35 GMT

Hi Guys,

I would need your help on the problem that I'm currently into...

Basically I have the data below.

I would like to extract the data having criteria:

(# of data occurences under same Group >= 2 OR total dollar under same Group >= 25) , AND
time range is less than 3 hours

Please note:

field "delta time" in "data wants" is row N - row N-1 on field "time" under same Group. For example: "delta time" = 5:51 in row 2 is coming from "time" in row 2 substracted by time in row 1.
sample remarks:
- row 4 & 5 got remarks Yes because within 3 hrs (delta time for both rows is 1:43) and total "dollar" is 32 (16+18) or total count is 2 (count for row 4 & 5).
- row 9,10,11 got remarks Yes because within 3 hrs (sum delta time from 9-10 & 10-11 is 2 minutes, coming from 0:01+0:01) and total count is 3 (count for row 9,10,11).

Thank you in advance

It is more complicated than I imaged . What you gonna do if you have data :

time dif

...............

08:00 04:20

09:00 01:00

11:30 02:30

You want

08:00 04:20 YES

09:00 01:00 YES

or want ?

09:00 01:00 YES

11:30 02:30 YES

Hi Xia,

Assuming the criteria of total dollar >=25 are met, then the output should be all of them, because:

no 1 and 2 data are < 3 hrs. & count >= 2
no 2 and 3 data are also < 3 hrs & count >= 2

Thanks for your assistance...
