Help with SUMX: Calculating Total Sales

[Anonymous]

Hi Everyone,

Okay so i have the following table (SALES) which i am importing in to PowerBI using Power Query:

Ret Trans Type	Style Barcode	Date	Sales Value	Sales Units
S	505336637308	24/07/2018	89.16	2
S	505336771951	23/07/2018	52.01	1
S	505336771951	28/07/2018	44.58	1

So now that i have imported my data, what i must do is Multiply the Sales Value by the Sales Units: (Sales Value * Sales Units).

Easy stuff, i create a calculated measure and get the following:

Style Barcode	Sales Value	Sales Units	Total Sales A
505336637308	89.16	2	178.32
505336771951	96.59	2	193.18
Total	185.75	4	743

Sales Tot A = SUM(SALES[[Measures]].[Sales Value]]]) * SUM(SALES[[Measures]].[Sales Units]]])  

However the Down Total is incorrect as i dont want it to be multipled on row basis, but instead the column 'Sales Total A' to be added from a colum prespective.

So isntead i use a SUMX in order to resolve the above and get the below result:

Style Barcode	Sales Value	Sales Units	Total Sales B
505336637308	89.16	2	178.32
505336771951	96.59	2	96.59
Total	185.75	4	274.91

Sales Tot B = SUMX(SALES, SALES[[Measures]].[Sales Value]]] * (SALES[[Measures]].[Sales Units]]]))

However, the issue i am experiencing now is that even though the Down Total is working as expected from the SUMX, the second record for 'Total Sales B' is returning the incorrect value: 96.59 * 2 IS NOT CORRECT.

I undertand that SUMX goes on a row by row basis to calculate, therefore as the data imported has two seperate records for barcode 505336771951 with 1 Unit each, i am assuming the reason i am getting unexpcted result is becuase SUMX is doing: 52.01 * 1 + 44.58 * 1 = 96.59.

The result i am trying to achieve is the following:

Style Barcode	Sales Value	Sales Units	Total Sales A
505336637308	89.16	2	178.32
505336771951	96.59	2	193.18
Total	185.75	4	371.5

Any help would be very much appreciated.

Thank you

Hey,

first I created these two measures

Total Sales Units = 
SUM('Table2'[Sales Units]) 

and

Total Sales Value = 
SUM('Table2'[Sales Value]) 

Then I created this measure

Total Sale SUMX = 
SUMX(
    VALUES(Table2[Style Barcode])
    ,[Total Sales Units] * [Total Sales Value]
) 

Instead of itereating across the table I'm iterating across the filtered barcode(s)

I guess this returns what you are looking for:

You are a legend @TomMartens

"Instead of itereating across the table I'm iterating across the filtered barcode(s)"... Makes Total Sense.

Thanks for the quick respon 🙂

I am not sure if I completely understand your math. Is sales value the unit price or the final price? If it is not unit price, is the unit price sales value/unit price?

Also your SALES TOT A formula seems to be wrong if Sales Value is the unit price

you need to create a calc col which is sales value * units

and then just sum that and you will get the required ans.

Sales Tot A = SUM(SALES[[Measures]].[Sales Value]]]) * SUM(SALES[[Measures]].[Sales Units]]])  

your sales tot A formula is summing the sales value of all products (89+52+44) and sum of all units(2+1+1) and multiplying this which is wrong. it should be sum(sales values * units)

Hi @Anonymous,

I had already attempted to create a Calculated Column, however, the second record would be incorrect that way.

This is is again due to having two seperarte records for Barcode: *1951 each having 1 Unit

Thanks for your responce 🙂

Style Barcode	Sales Value	Sales Units	Total Sales A	Sales Tot B	Total Sales Calculated Column
505336637308	89.16	2	178.32	178.32	£178.32
505336771951	96.59	2	193.18	96.59	£96.59 (Wrong)
	£185.75	£4.00	£371.50	£274.91	£274.91
