# Set Analysis/If statement date range query

Hello,

I have the below data as an example and I am struggling to get correct formula for sales before and after "Date Change Made" per project and also count of number of weeks before and after "Date Change Made", regardless of whether there is a transaction in a week or not.

[ProjectData]:

Project Name, SKU     , Date Change Made

A                    , 123      , 28/02/2018

A                    , 456      , 28/02/2018

A                    , 789      , 28/02/2018

B                    , 123      , 01/02/2018

B                    , 101      , 01/02/2018

B                    , 102      , 01/02/2018

[SalesData]:

Invoice No, Invoice Date   , SKU  , Sales Total

001,            01/01/2018     ,123     ,100

002,            01/02/2018     ,456     ,100

003,            01/03/2018     ,789     ,100

004,            01/01/2018     ,123     ,100

005,            01/02/2018     ,101     ,100

006,            01/03/2018     ,102     ,100

007,            01/01/2018     ,789     ,100

[Calendar]:

Invoice Date, YearWeek

01/01/2018  , 2018-01

01/02/2018  , 2018-05

01/03/2018  , 2018-09

I want to sum sales per project which is fine.

I then want to sum sales per project where the invoice is within the 6 months prior to "Date Change Made" per project.

The same for sum sales where invoice is after "Date Change Made" per project.

For sales before and after i have something like this:

Sum(if([Sales Invoice Date]<[Date change in front of customer] and [Is Sales Account]='Yes',[Sales Total (GBP)]))

Sum(if([Sales Invoice Date]>=[Date change in front of customer] and [Is Sales Account]='Yes',[Sales Total (GBP)]))

Can this be done in set analysis instead when there are different "Date Change Made" values?

For the count of weeks I have this:

count(distinct if([Sales Invoice Date]>=Date(addmonths([Date change in front of customer],-6)) and [Sales Invoice Date]<[Date change in front of customer] ,[Sales Invoice Date.Calendar.YearWeek]))

But I need to count all YearWeek in the past 6 months and not just those that have a transaction in them.

Any help is appreciated.

Would you be able to share the expected output (numeric output) based on the sample you have provided?

• ###### Re: Set Analysis/If statement date range query

Hello,

Output for the example data there would be:

Project      /   Date of Change / Sales Before   /  # weeks (6 months prior to date change) /   Sales After  /   # Weeks (up to today)

Project A   /   28/02/2018     /      300               /    27            /  100              / 4

Project B   /   01/02/2018    /       200               /    27            /  200              / 8

The calendar does contain missing dates and therefore missing weeks which need counting.

There are 7 invoices total to £700 but £800 will appear in the results as sku 123 can appear in both project results.

Thanks

So, far I got this.... why is A not 400 for Sales Before?

Shouldn't we include these 4 rows?

Invoice No, Invoice Date  , SKU  , Sales Total

001,            01/01/2018    ,123    ,100

002,            01/02/2018    ,456    ,100

003,            01/03/2018    ,789    ,100

004,            01/01/2018    ,123    ,100

005,            01/02/2018    ,101    ,100

006,            01/03/2018    ,102    ,100

007,            01/01/2018    ,789    ,100

Hi ,

Yes sorry you are correct, project A before date of change should be 400.

I think I have it working with if statements similar to what you have. I was just tried to do it with set analysis but i am struggling there as even using max and aggr it is evaluating to the wrong dates.

Thanks

• ###### Re: Set Analysis/If statement date range query

Set analysis is evaluated once per chart.... in your case, the [Date Change Made] is different per project which will essentially make it unusable in set analysis. If statement is the way to solve this problem....

• ###### Re: Set Analysis/If statement date range query

OK I will just carry on with the IF statements for now then as they seem to be working ok. It is a relatively small data set so it shouldn't case any performance issues.

Many Thanks

Use something like this when Project Name is your dimension -

One obervation - You have common SKU '123' for both project A and B, so I think one invoice row for SKU 123 will be double counted for Project A and B.

• ###### Re: Set Analysis/If statement date range query

Hi,

That doesn't quite give the correct answer.

Take this real data as an example.

For project name = 'no_description_SKUs_20180227' total sales is £160.09. The "Date Change Made" for this project is 28/02/2018.

So counting sales in 12 months prior to today should add to £160.09 using the invoice data on the right.

However it is missing the transaction on 10/05/2017 as it is not calculating the "Date Change Made" correctly. Another project has a "Date Change Made" of 29/05/2018 so it must be using this and not 28/02/2018

Seems to be taking the max date of all projects and not per project.

Thanks
