Calculate monthly distribution between two tables

Anonymous — Wed, 27 Apr 2022 09:29:57 GMT

Hi,
I've been trying to create a report which estimates the monthly distribution based on two tables.

Table 1 contains Year-Month, country and weight based on shipping data.

Year-Month	Country	Weight Kg
2021-01	Norway	15
2021-01	Canada	2
2021-02	Norway	10
2021-02	Brazil	3

Table 2 contains Year-Month, weight, and attributes based on transactions.

Year-Month	Weight Kg	Attribute 1	Attribute 2	Attribute 3
2021-01	12	A	A	B
2021-01	5	B	C	A
2021-02	3	C	B	A
2021-02	9	B	B	B

I'm trying to estimate the distribution of each attribute with each country based weight distribution per month.
My plan is to calculate the total attribute weight per month, get a ratio and then distribute it to each country.

The total weight per month doesn't need to add upp to the toal attribute weight per month, only the ratios are important.

In this example I want the following:
2021-01: Total attribute weight 17 Kg, 12/17 has [A,A,B] and 5/17 has [B,C,A]
2021-02: Total attribute weight 12 Kg, 3/12 has [C,B,A] and 9/12 has [B,B,B]

The end table should then show

Year-month	Country	Attribute Weight Kg	Attribute 1	Attribute 2	Attribute 3
2021-01	Norway	12*(12/17)	A	A	B
2021-01	Norway	12*(5/17)	B	C	A
2021-01	Canada	5*(12/17)	A	A	B
2021-01	Canada	5*(5/17)	B	C	A
2021-02	Norway	10*(3/12)	C	B	A
2021-02	Norway	10*(9/12)	B	B	B
2021-02	Brazil	3*(3/12)	C	B	A
2021-02	Brazil	3*(9/12)	B	B	B

Any help regarding this would be greatly apprechiated!

Where do you want to do this? In Power Query or DAX? I suggest you do it in Power Query.

Hi Anonymous ,

I created a sample pbix file(see attachment) for you, please check whether that is what you want.

1. Create a relationship between Table 1 and Table 2 base on the field Year-Month

2. Create a measure as below

Attribute Weight Kg = VAR _selym = SELECTEDVALUE ( 'Table 1'[Year-Month] ) VAR _selcountry = SELECTEDVALUE ( 'Table 1'[Country] ) VAR _t2sqty = CALCULATE ( SUM ( 'Table 2'[Weight Kg] ), FILTER ( ALLSELECTED ( 'Table 2' ), 'Table 2'[Year-Month] = _selym ) ) RETURN SUM ( 'Table 1'[Weight Kg] ) * ( DIVIDE ( SUM ( 'Table 2'[Weight Kg] ), _t2sqty ) )

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
