问题 Need some help here grouping a measure result for a visual in PowerBI using DAX. I have a table that displays all visits by certain customers (Visits table). I have a measure that counts the number of visits for each day, and I have a date slicer (visit day). The results of this measure usually range between 1 and 10. I am trying to see a frequency of customers visits per year. If they have 1 = single visit 3 or more visits = returning customer 7 or more visits = frequent customer. I am

问题 I am looking to do a QoQ calculation in a table. The problem I am facing is that I do not know how to calculate the previous value while the current value also shows. I would then use that field to create a difference or % difference. Hopefully the following example makes it clear. Sample data: Quarter | Year |Product| Measure Q1/19 | 2018 | A | 22 Q1/19 | 2018 | B | 61 Q1/19 | 2018 | C | 187 Q2/19 | 2018 | A | 121 Q2/19 | 2018 | B | 31 Q2/19 | 2018 | C | 15 Q3/19 | 2018 | A | 68 Q3/19 | 2018

问题 I need to sum all values in each row and display them in a calculated column. As I deal with lots of columns in lots of tables, adding something like CalculatedColumn = 'public table_name'[column1] + 'public table_name'[column2] + ... + 'public table_name'[column528] is really inefficient. Is there a shorter way of doing this? 回答1: Yes, there is. You should "Unpivot other columns" and then "Group By" using the Query Editor. Suppose this dataset: item;col1;col2;col3;col4;col5 apple;1;2;3;4;5

问题 Background: I have posted a question regarding a custom function in Power Query that I found in a blog by Chris Webb which I have already got an answer to.But now I have another question related to the same custom function. One of the amazing steps in that custom function is the recursive step at the end named " OutputTable " which calls itself using a if statement, basically making it a loop . Below is the step: OutputTable = if NextColumnNumber>(Table.ColumnCount(ExpandedTable)-1) then

问题 In my data set, each PolicyNumber can have multiple ClaimNumber . So all I want to do is to get Unique PolicyNumber and Count the number of Claims ( ClaimNumber ) for each PolicyNumber . (Like a pivot table in Excel) In Power BI I click Edit Query , click Group By , specifying the column I want to group on which is PolicyNumber , giving the name to new column ( CountOfClaims ), Operation - Count Rows ...but I am unable to choose Column value. For some reason its inactive. It works if I need

问题 I am working in POWER BI and trying to calculate a DAX expression for the rolling total of the previous month. I have a filter where I select a certain month, I would like to calculate the rolling total for the previous month. Below is the calculation that works perfectly to calculate the rolling total for the selected date range. How can I calculate the previous months rolling total? Rolling_Total_Current_Month = CALCULATE( SUM(SalesInvoice[Sales]) ,FILTER(ALLSELECTED(SalesInvoice),

问题 I'm a beginner in coding and am not familiar with "M" modeling language. I have an XML file that I want to use to load the data in Query Editor. In the Query, I need to expand only the table columns with a specific name below: view viewfolder Attribute:name I have found the following post where they give a function by Chris Webb for expanding all the lists(below code). = (TableToExpand as table, optional ColumnNumber as number) => let ActualColumnNumber = if (ColumnNumber=null) then 0 else

问题 This question is not limited to Power BI, but it will help me explain my problem. If you have more than one table in Power BI, you can establish a relationship between them by dragging a column from one table to the other like this: And you can edit that relationship by clicking the occuring line: And by the way, here are the structures of the two tables: # Table1 A,B 1,abc 2,def 3,ghi 4,jkl # Table2 A,C 1,abc 1,def 2,ghi 3,ghit This works fine since column A in Table1 consists of unique

问题 I know this issue has been posted many times before, but I was not able to get a solid/working solution. I am trying to figure out a workaround for refreshing dataset with Custom functions over Power BI service. My query looks like the following: let Clients = Json.Document(Web.Contents("https://api.createsend.com/api/v3.2/clients.json")), #"Converted to Table" = Table.FromList(Clients, Splitter.SplitByNothing(), null, null, ExtraValues.Error), #"Expanded Column1" = Table.ExpandRecordColumn(#

问题 I am new to Microsoft Power BI designer and noticed this documentation that mentions being able to do a many to many join within the tool. When I try to do the many to many join, I receive an error that says "You can't create a relationship between these two columns because one of the columns must have unique values. Am I doing something wrong? Thanks in advance. 回答1: This is an error in the documentation. As you've noted, you can't specify this in the relationship dialog. Many to many
