Hi all,

I have a set of stores which I use as a mapping key. These set of stores will be filtered into either Tier 1 or Tier 2 stores. I have the revenue of each store by month and the size of each store in the table as well.

Is there anyway I can calculate this using a calculated column so that when I add in a filter and group sums tgt, the aggregated revenue/sqm is the correct amount?

Basically I just want to calculate an revenue/sqm which I can put in my pivot table. Thanks

Please bear in mind that my data is by month, but I'm analysing by year so if I sum up the size column, it gives me a value too big, but if i use average, it gives me a value too small.

My head is about to explode trying to figure this out so I'd appreicate any help whatsoever.

Oh! You have a Groups/Super Groups problem on your hands. So in your size measure, you are going to need to use SUMMARIZE to get the AVERAGE of each individual store (which will give you the actual store size) in the group and then just use SUM to SUM the AVERAGE of the sizes. See this article:

Sorry, none of that made any sense until you mentioned your related table for grouping.

Data is like:

A jan 1000 500
A feb 1000 700
B jan 2000 600
B feb 2000 800
C jan 2500 1000
C feb 2500 900

Size never changes across months, but revenue will.
I have relationships on the store which will group them in my pivot, so for example A and B will be tier 1 location, so I need the average to kind of "average" the unique store sizes then Sum the sizes of each unique store.

Thanks!!

Does the square meter of you store change every month? Because if you had data like:

Store,Revenue,SQM,Month,Year

Store1,\$1000,10,1,2018

Store1,\$2000,10,2,2018

If the square meters of the store is the same then if you take the average of it, you should get the square meters of the store regardless of how you aggregate. Or just use MAX or MIN? Need to see data.
