Wrong calculations for rows in Power BI matrix - powerbi

I am trying to calculate market share, but struggling with doing it correctly.
I have a matrix where I have Category, Name as rows, Channel as column, and Market Share as value.
Also In my dataset I have columns ABS_COMPANY (with sales inputted there if company = "A", so there are some blank ones), and ABS_TOTAL (with sales inputted in each row)
so my measure Market Share:
Market Share = SUM(table\[ABS_COMPANY\]) / SUM(table\[ABS_TOTAL\])
This correctly calculates values for each Category, but when I open the drop-down to see Name, Market Share of each Name equals to 100%. What is the problem and how to fix it?
e.g. What is now:
Market Share
Pens 43%
pen 1 100%
pen 2 100%
pen 3 100%
Pencils 29%
penc 1 100%
penc 2 100%
penc 3 100%
I've tried using Calculate(), but it does not work in a way I want to.
Unfortunately, I cannot share the data as it is sensitive.
Structure of dataset:
NAME STRING
CATEGORY STRING
CHANNEL STRING
ABS_COMPANY DECIMAL(20,2) - value of sales for each name
ABS_TOTAL DECIMAL(20,2) - it is a value grouped by CHANNEL AND CATEGORY at the backend

DAX & Power Query - Removing transaction line if sale is returned

First time posting, thanks in advance !
I have a simple sales table acting as a data source.
In this table I have all my dimensions and facts, the data model is not organized as a star schema.
I believe this question does not require the data model to be optimally built.
One column tracks the Sales Quantity and shows -1 if the item is returned.
In Power Query.
I wish, for all returns, to eliminate the line with the -1, but also the associated line with the +1 sale.
I do not wish to simply filter by the Invoice Number and remove it, as in the same invoice I may have other items who were not returned.
I wish to have in my final table only final records.
Thank you
Did not manage to identify a way to tackle the issue in Power Query as of yet.
Edit, addition of further context
Dataset abstract:
I would like to keep the green row and remove the yellow ones.
One invoice features three lines, two for one item being sold and returned, and one for an item being purchased for good. That latter one is to stay in the records.

Because I do not know the exact nature of your data, I will give you a general solution for your problem, which will help you immensely.
First, I will transform your data into facts and questions. Then I will answer the questions depending on my experience analyzing many different datasets; last but not least, I will provide you with the solution.
Facts,
[Sales Amount Include Tax] column values for Return Sales are negative numbers because excel format negative numbers by including them with parentheses, as your data shows.
The Original Sale record and the Return Sale record must have the same values for these columns, which we will use to know the Original Sales record:
The absolute value for the [Sales Amount Include Tax] column.
[Invoice No], [Department], [Sub Dept], [Sub Dept GROUP], [Item Code] columns.
This point is critical because we will use these columns to know the Original Sales record.
Questions,
Is the Item code column value similar to the original sale row and the returned sales row?
My answer: It should be because you are returning the same item that the Item code column describes, but I am concerned that your data shows that the first two rows don't have the same Item code. Is it by mistake?
Is the Sales Quantity column always filled with -1, even if the original sales quantity was, for example, three pairs of shoes?
My answer: The Sales Quantity column should describe the number of items someone bought, so if I originally bought 2 things but didn't like them for a reason, I will return two items so that the column value will be -2.
If my above assumptions are correct, you need to do the following in the Power BI query:
1. Import your Sales table to Power BI. See this image that shows the test data I used.
2. When you import your data and see it in the Power Query Editor, you will see that the Sales Amount Include Tax column value shows minus rather than parentheses for Return Sales Rows, as you can see in this image.
3. Create a copy of your Sales table and Rename it to Returned Sales, then filter this table to include only [Sales Amount Include Tax] that are less than 0, as you can see in this image.
4. Filter the Sales table to include only [Sales Amount Include Tax] greater than or equal to 0, as you can see in this image.
P.S. Now comes the fun part :)
1. In Returned Sales table, add a custom column name it ReturnedSaleFlag, then give it a value of 1, as you can see in this image.
2. Change ReturnedSaleFlag column type to Whole number.
3. In Returned Sales table, transform [Sales Amount Include Tax] to an Absolute Value, as you can see in this image.
4. Now you need to return to the Sales table and merge it with Returned Sales table using multiple columns which are the column listed in the second point of the fact section, as the image shows. Also, see this link that describes how to Merge query based on multi columns.
5. Expanded the new Returned Sales column in Sales table and only select ReturnedSaleFlag column and make sure to remove the check from use original column name as a prefix, as the image shows.
6. Finally, all your previous hard work created a flag in your Sales table that will let you know the Sales record that had been returned. :)
7. Now you filter the Sales table to keep the records that only have null values for the new ReturnedSaleFlag column then remove this column, as the image shows.
8. In the end save and apply and analyze your Sales and your extra info in the Returned sales.
I hope I helped in a way; if so, please mark this as an answer and vote for it :)

Power Bi, Return percentage of grand total but the column's values are text

I am trying to return the percentage of the grand total from #number of clients using the second and fourth columns. The number of clients values are text and are collected using Count('Table'[Column]). That is where I have run into issues. When I try Countrows() or AllSelected() to try and work around it, it returns all the rows and doesn't keep the filters I have set.
My current measures:
Client Total = COUNTA('Table'[Client_Name])
% with at least 1 document = DIVIDE(SUM('Table'[At Least 1 Document Sum]), [Client Total])
Right now, it only calculates the percentage based on the filtered # of clients in the same row versus the grand total. I am hoping to have it use a dynamic grand total that is shown at the bottom of the table.
[Current Table] (https://i.stack.imgur.com/IG254.png)
Here is my solve
Measure Name = CALCULATE(COUNTROWS('Table'),ALLSELECTED('Table'))
Then:
Measure Name = SUM('Table'[At Least 1 Document Sum])/'Table'[Measure]

Create a custom table inside a dax measure and count number of values of an specific column

I'm practicing my Power BI skills. I've downloaded a csv file which contains data about olympic games. The dataset has many columns, such as country, athlete name, year, sport, event, medal which the athlete has won, olympic city, etc.
The problem is that I want to create a bar graph that display country name by medal types count. However if create a graph "Country" by "Medal" from original csv it will not display the correct numbers of medals, because if a country wins a medal in a team sport (like volleyball or football) it should count as only one medal, and not the sum of all medals of all athletes in that team. This could be solved by removing Athlete column and selecting distinct values of "Event" column, like creating a table using the following formula:
Table 2 = CALCULATETABLE(ALLEXCEPT('summer (3)','summer (3)'[Athlete]),DISTINCT('summer (3)'[Event]))
However, I don't want to create a new table, because I would have serious problems with relationship between them (I have no idea how to do it, to be honest). So I want to create a measure. I created the following measure:
Medal count = COUNTX(CALCULATETABLE(ALLEXCEPT('summer (3)','summer (3)'[Athlete]),DISTINCT('summer (3)'[Event])),'summer (3)'[Medal])
It is showing the correct number of all medals in olympic games history (untill 2012). However, for every country, its showing the number of gold medal, silver medal and bronze medal with the same number (the total number of olympic medals 14753). It's not filtering by the number of rows for that specific country.
The same number also appears if I select any medal type from filter option (Gold, Silver or Bronze).
I have no idea how to fix this. How can I create a measure that shows the correct number of medal type for every country?
This is what I would do. First I will create an "id" column if I haven't had that, then I will do the distinctcount on that.
The DAX for the id column should be something like this:
debug_id = CONCATENATE(Table['Year'],CONCATENATE(Table['Sport'],CONCATENATE(Table['Discipline'],CONCATENATE(Table['Country'],CONCATENATE(Table['Event'],Table['Medal'])))))
then you can basically drag and drop this field onto the x-axis (y-axis and legends stay the same) and select Count (Distinct). If you really want the measure for this, it should be quite straight forward like:
Medals count = DISTINCTCOUNT(Table['debug_id'])

How to deal with multiple ids multiple categories table to reach THIS on Power BI

I have a problem that i was trying to solve 3 days ago and i'm not able to.
I have the following tables:
Companies
company_id
sales
1
2000
2
3000
3
4000
4
1000
Categories
company_id
category
1
medical
1
sports
2
industrial
3
consumption
4
medical
4
consumption
All i want to reach is a COLUMN CHART with a CATEGORY SLICER where i choose the category and i see the TOP 5 companies by category and sales. Yes, in this example the TOP is not needed but in my real case i have 400 companies so i want to:
Select and Show only the required category.
In that category, show only the 5 better companies by sales.
The problem here is Power BI takes all the companies for the TOP N filter so if i choose a category, and also try a top 5, if the companies are not in the TOP5 all companies list, it doesn`t show anything.
Thanks!
If you always want to show the same Top N values in your visual, you can use the filter pane to achieve that.
Below a walk through:
The to add the Top N filtering, I add the following:
It is in Dutch, so a little clarification:
I add a 'filter on this visual'
I selected Populairste N, which is Top N
And as a value I drag and dropped the maximum of sales.
Results:
Things to keep in mind:
You are using a many to many relationship, make sure that this is activated in the Power BI model.
Make sure the direction of filtering is from category to sales, otherwise the slicer will not work. It looks like this:

All rows and total of the rows showing same values in power BI

I am trying to show "Some Column Name" against "Total Amount" in Power BI.
I am expecting the following results:
But instead it's showing me the following results:
The current data type is "fixed decimal number" I tried changing it to "Decimal number" or "Whole Number" but it did not work.
Any suggestions?
The reason why you have a single repeating value is because you did not create a relationship in powerbi model. If for example you have two tables Sales and Staff and you want to sum all staffs sales.
if no relationship created between table in power BI
The output will look like this
However when a relationship is created between the tables
The output will be correct
This is almost certainly the result of a many-to-many relationship in Power BI. In Power BI if there are connections between two (or more) tables that evaluates to a many-to-many relationship then Power BI is unable to make a distinction between any two rows and instead will project the same value for any given row placed in a visual.
Here's an easy way to visualize this:
Table 1 Table 2
Product | ID AmountSold | ID
Widget 1 10 1
Smidget 1 20 2
Gidget 2 5 1
When you join these Power BI can't tell the difference in Sales between Widget and Smidget because they have the same ID. As far as Power BI knows Widget could have sold 0 and Smidget sold a total 15, or Widget sold a total 5 and Smidget sold a total 10, etc.
As a result of this many-to-many relationship Power BI panics and evaluates them to be the same result because it can't determine what is right. Widget and Smidget both sold a total of 15:
Visual
Product | AmountSold
Widget 15
Smidget 15
Gidget 20
You're experiencing the same issue in your data model, although it is undoubtedly a much more complex relationship than the one I just laid out. You need to go back and determine what table(s) are experiencing a many-to-many relationship and fix the issue. Based on the information you've provided it can't be done from here.
