## Combine multiple DISTINCT statements to get the MIN value

Hello everyone,

I'm new to the world of Power BI and I need your help.

My goal is to find the lowest value ('Price') filtered by a combination of two columns ('Product_ID' and 'Month Number'). Take this table as an example:

Total Sales Table:

 Contract_ID Product_ID Month_Number Price 01 1001 1 2,34 02 1001 1 2,22 03 1001 1 2,45 04 1001 2 2,19 05 1001 2 2,37 06 2002 2 5,69 07 2002 2 5,14 And so on ... ... ...

That is what I want to achive:

 Contract_ID Product_ID Month_Number Price Best_Price perProduct and Month 01 1001 1 2,34 2,22 02 1001 1 2,22 2,22 03 1001 1 2,45 2,22 04 1001 2 2,19 2,19 05 1001 2 2,37 2,19 06 2002 2 5,69 5,14 07 2002 2 5,14 5,14 And so on ... ... ... ...

This is what I had tried, but it didn't work:

`Best_Price per Product and Month =CALCULATE(MINX(Total_Sales, Total_Sales[Price]),DISTINCT(Total_Sales[Product_ID]),DISTINCT(Total_Sales[Month_Number])`

Any sugesstions / ideas how to solve that issue?

You would help me a lot! Thanks in advance 🙏

Best,

Felix

See if this works for you:

``````Best Price =
CALCULATE(
MIN('Table'[Price ]),
REMOVEFILTERS('Table'[Contract_ID], 'Table'[Price ])
)``````

Because Month is a number and the way you have your data @Anonymous , you ned to make sure that the column is not summarized or the results will not be correct.

Thanks for your help! (Sry for the late reply, I was on vacation.)

I testet your solution on a small "testing data set" and it worked completly fine, but not on my "real" data set I'm working on.

Could you explain why you've selected the column 'Contract ID' for the REMOVEFILTERS function?

Best,

Hi @Anonymous  - sorry just getting back to you. Missed the notification.

I didn't want the filter context from the table visual that was passing the current contract ID to affect the measure, so I removed that filter. The measure looks at all contract IDs to get the results. It keeps the filters though for the month ID and product.

I used the function ALLEXCEPT to solve my problem, but without you I would not have figured it out. Thanks! 💛

Great @Anonymous !

Yup - ALLEXCEPT, REMOVEFILTERS, ALL, etc. within CALCULATE are different ways of doing the same thing depending on the circumstances. ALLEXCEPT can be more efficient depending on how many fields you have to remove the filters on.
