PLEASE HELP: sum, aggregation and set analysis

[rajkapoor1]

@hi All,

I have tried to create a logic using set analysis which combines both the sum and aggregation function but failed to get the right method. Here's a simple table to illustrate what I wish to achieve:

I would like to count the number of distinct store ids if the total product sale for the whole month for the given store id is less than a threshold value.

In the example below, the threshold value for product sale is 50.

So if you count the number of STORE ID whose given Product Sale is less than 50 for the whole month, then the result is 1 (Store ID A).

Please note that the table is not complete and contains data for only 4 days.

I've tried this function in a text box but I'm getting errors:

=count( aggr(sum({$<[City] = {'London'}, [Month]={'Jan'}}[Store ID])<50) DISTINCT [Store ID])

Not very sure whether that's the right logic. I would really appreciate your help on this one. Thanks

Store ID	Month	Date	Product Sale	City
A	Jan	01/01/2018	10	London
A	Jan	02/01/2018	5	London
A	Jan	03/01/2018	10	London
A	Jan	04/01/2018	5	London
A	Feb	01/02/2018	96	London
A	Feb	02/02/2018	20	London
A	Feb	03/02/2018	15	London
A	Feb	04/02/2018	30	London
B	Jan	01/01/2018	61	London
B	Jan	02/01/2018	13	London
B	Jan	03/01/2018	25	London
B	Jan	04/01/2018	21	London
B	Feb	01/02/2018	96	London
B	Feb	02/02/2018	20	London
B	Feb	03/02/2018	15	London
B	Feb	04/02/2018	30	London

stalwar1‌ Could you please help here? Many thanks!

You want this only for Jan?

May be this

Count(DISTINCT Aggr(If(Sum({<Month = {'Jan'}>}[Product Sales]) < 50, [Store ID]), [Store ID], Month))

[sunny_talwar]

Or this for all months

Count(DISTINCT Aggr(If(Sum([Product Sales]) < 50, [Store ID]&Month), [Store ID], Month))

Hi stalwar1‌ ,

Just to give you some context:

I have created a variable and linked it to a drop down that shows different months. By clicking on each month, you can see the total number of stores (store id) that have sold less than 50 items for the selected month.

So yes, I would like to count the STORE ID for every month.

Many thanks,

RK

Let me try this and get back to you! Thanks

[sunny_talwar]

So, at any given point of time, you will only be looking at stores for a single month, is that right? Try this

Count(DISTINCT {<[Store ID] = {"=Sum({<Month = {'Jan'}>} [Product Sales]) < 50"}>}[Store ID])

[rajkapoor1]

Yes that's right. I would also like to include the City as well. I want to only filter by London. Where do I place it in the set analysis logic you just showed me? Thanks

[sunny_talwar]

May be this

Count(DISTINCT {<[Store ID] = {"=Sum({<Month = {'Jan'}, City = {'London'}>} [Product Sales]) < 50"}, {<Month = {'Jan'}, City = {'London'}>}[Store ID])

[rajkapoor1]

Just wondering - would you not use an aggregation function to sum up the product sale values for each store ID and then see whether the value is < 50 to be able to count that specific store ID. It's almost like creating a separate table and getting the count:

Store ID	Month	Product Sale	City
A	Jan	30	London
A	Feb	161	London
B	Jan	120	London
B	Feb	161	London

Does the logic you mentioned actually sum up the product sale at an individual store id level? Apologies if I'm asking silly questions - would like to understand your logic in depth.

Thanks,

RK
