Incorrect Sum in POWER BI DAX

[kleith]

Good morning, I have a problem when performing the sum() function in power bi. It makes me feel bad. What's happening? I have the following values ​​in the square_meters column:

-8832​

-7452​

-4726​

-4715​

-2975​

-2951​

-2181​

-2157​

-2002​

-631​

7452​

7452​

8130​

8832​

8832​

8832​

The sum of all this is: 82,267 (including the negative values ​​that are credit notes) which is correct.

But, when using the addition function it brings me the following result: 92,612, and the values ​​that are being added are the following:

-8832​

-7452​

-4726​

-4715​

-2975​

-2951​

-2181​

-2157​

26496​

As you can see, in the incorrect sum it adds values ​​that are not in my table and the values ​​that are in my table are the numbers that I placed at the beginning. I attach an excel with the correct meters and the incorrect meters. I would appreciate it if you could help me understand what is happening. I already checked other fields and filters but the result is still the same. Thank you so much.

Hello @kleith,

Here are some steps you can take to try troubleshooting:

• If there's a relationship with another table, ensure that it's correctly set up, and there aren't any unexpected filters propagating from other tables.
• In the visual level, page level, or report level filters, ensure that there aren't any filters applied that might be altering the total.
• Ensure that there aren't any duplicated rows in your table. You can check this by creating a table visual and sorting by the square_meters column.
• While using SUM() should work for simple column addition, you can also try SUMX(), which sums up after evaluating each row
• If there are decimals involved, consider the effect of rounding. It might not be noticeable on individual rows, but it can affect the total.

Should you require any further assistance, please do not hesitate to reach out to me.
