Wrong calculation

[Anik]

 Here I've encountered a problem. In 2013, the number of sales was 12,760. When I dragged the (country) column into the Columns section, an additional blank row is created. Whatever columns (country/city/region etc.) I dragged into the matrix  columns section, the problem was same.

Hi @Anik ,

Your Date dimension relates to the delivery date key field in Fact table, and you do have records with blank delivery date in the fact table. This is why the dimdate field is empty, and power bi won't filter them out by default in case you need them!

If you want to avoid that, you could add a filter on the visual/page/report to exclude those cases.

Hi @Anonymous and @Greg_Deckler , the left image was taken from a book, the right one was done by me. I tried and inspected everything according to my knowledge. I am sure I cannot hammer on the right place due to my inexperienced eyes. I have attached the practice file. Could you please go it over and tell me what's the mistake I made so that I don't make the same mistake over and over again?  Thank you 😊  https://drive.google.com/file/d/1qFkzdEYZw3PffdZz3yngv5xluowB4TF5/view?usp=sharing

@Anik Try using Invoice Date Key instead to form your relationship. You have blanks in your Delivery Date Key.

Hi @Greg_Deckler , @Arentir , thank you so much 😊. Next time I am going to keep in mind about the blank cells while making relationships.

Hi,

In the Delivery Date key column of the Fact sales table, there are some blank cells.  Plug them in with Dates.

Hope this helps.

@Anik There is likely something going wrong in a relationship between two tables. You tend to get blanks when rows don't match up. For example:

Year

2013

2014

2015

Fact

Year   Value

2012  2

2013  5

2014  6

2015  2

Assuming a relationship between the two tables on Year if you used Year from your Year table and a sum of Value from your other table you would get a blank row that is essentially the 2012 data.

This is very basic, but have you checked the Calendar YEar column for those 55 entries to ensure they are formatted as date? (I assume yes, as I am assuming from your post that when no additional column is added in, the report correctly shows 12,760?
