Record evolution analysis

Wed, 20 Aug 2014 10:44:34 GMT

Dear QVers,

I need to create a chart to show how opportunities have changed from one period to another (i.e week 30 against week 32). For example, if a record moved from Sept to July it will be flag as “Move In” or if the value of a record in week 30 was 150 and then 100 in week 32 then a “Value adjustment” category will be assigned to this record.

In the data we have all the records with a Date of Extraction field. The challenge is that I cannot do the above logic in the script because the user selects the periods of data extraction (i.e. from week 30 to week 32 or from week 20 to week 24) to compare the records. The questions are how can I:

Check if the record in start week (i.e. week 30) exists in end week (i.e. week 32). I am using p() function now, but I dont know if this is the best solution.
Check how the records have changed (i.e if the order date moved from Sept in week 30 to July in week 32 or if the sales stage changed from Prospect to Order, etc)
Assign its value to the specific category (i.e. Move in, Move out, Value adjustment, Hit)

Please help!

See the attached qvw for a first try. I'm pretty sure you'll find things wrong with it, which will give you an opportunity to make the business logic more explicit.

Hi Gysbert,

Thanks for the hint. I will check it and read more about Alternate States since I am not too familiar.

BR,

Hi Gysbert,

How could I translate it to a bar chart like this?

Hi,

I wrote an expression like:

Sum(aggr(if(only({AS1}[Date Expected])>only({AS2}[Date Expected]),sum({AS1}Value)),RecordID))

And I got the chart

Tks!
