Power Pivot :: Formula For Row Wise Weighted Average
Apr 22, 2015
I have a table in `PowerPivot` which contains the logged data of a traffic control camera mounted on a road. This table is filled the velocity and the number of vehicles that pass this camera during a specific time(e.g. 14:10 - 15:25). Now I want to know that how can I get the average velocity of cars for an specific hour and list them in a separate table with 24 rows(hour 0 - 23) where the second column of each row is the weighted average velocity of that hour?
In a separate `PowerPivot` table I have 24 rows and 2 columns(column1 is for hours and column 2 for weighted averages) and when I enter my formula, the whole rows get updated with the same number. My formula is:
How can I apply "Min" formula under a "new measure" (calculated field) within a pivot table under Power pivot 2010?Can see that neither does it allow me to apply "min" formula directly "formula box" nor could find any other option.Intent formula: "=Min(1,sum(a:b))" this isn't allowed so all I can do is "=sum(a:b)".
I have written a simple DAX calculated column formula using SEARCH and got an error: It tells the text "PWP" cannot be found but as you can see the screen shows this text exsist within "Promotional Claim"The same happens when I try FIND function.
I have a calculated measure that is "Cost Per Patient:=sum([ActualCost]) / sum(Patients[PatientCount])" and it works fine. I'd like to be able to create another calculated measure based on "cost per patient" that uses min, max and average of "cost per patient" but dax wont let me.
I've read about dax calculate but not sure how to use it in my situation. Here is background on the problem:
There are 2 fact tables, prescription cost and patient count. Both are related by a practice dimension. The practice dimension has a geography hierarchy of county - town - practice.
The "Cost Per Patient" works fine with the geography hierarchy. By that I mean it shows the correct value when looking at the different levels. For my new calculation, for example looking at the list of counties, I want to use the min, max and average of "Cost Per Patient" of all counties. To break the problem down, I was going to start with creating and testing separate calculated measures for min, max and average and that's where I am stuck.
My understanding of the problem is it's something to do with the context of where the calculation is being made. As I want to perform the min, max and average on all the children of the parent. This article explains it but I can't figure out how to apply it to my situation [URL] ....
This is an SPC chart controlled by a slicer that operates a powerpivot table. This is then copied (by cell formula) into a "normal" table where the average, UCL, LCL and Erlang are calculated which are just basic calculations involving average and standard deviation. To make it work the values in the Average, UCL,LCL and Erlang must be repeated all the way down the table to create the chart. In the current format it works well and using a standard table keeps the chart range dynamic.
However this is a very clunky solution involving repeating the data tables in excel. I need to create dozens of charts and it will get large and slow.I would like to create the whole thing in a powerpivot table using measures so i can use powerpivot charts and ultimately powerBI. The data column PasID is a text column so I need a measure that calculates the "count of PasID" for each day(the row labels) and then repeats that value down a whole column in the same way the standard table does. I couldn't figure out how to get the correct number repeat down the whole column, which measures to use,Whether to create calculated columns in the data model or any of it. SO I need to be able to get a count of a text column then display the average of that count in a second column all the way down.
I'm trying extract a column from the table based on certain Conditions: This is for PowerPivot.
Here is the scenario:
I have a table "tb1" with (project_id, month_end_date, monthly_proj_cost ) and table "tb2" with (project_id, key_member_type, key_member, start_dt_active, end_dt_active).
I would like to extract Key_member where key_member_type="PM" and active as of tb1(month_end_date).
I am trying to build various reports that compares data over time. I have one that measures Year Over Year % difference for number of incoming projects. I managed to do that easily by calculating the following
Where Projects is the metric in question, TrendData is the table that contains project data and CalendateDate is the Date Table. But now I am trying to compare the same YTD projects data to number of projects that came in the last 6 months. How do our projects compare to average number of projects that came in last 6 month period.
I tried the the DATEADD function instead but got no luck and data came out wrong!
I am trying to show images in a product listing in power view.I work with an excel 2013 desktop version based on an office 365 pro account.I did the following steps:
import of an excel file with an article list via power query and loading the data to the data model import jpg images from a folder via power query, setting content as binary type and loading the data to the data modellinking both tables in power pivot--> manage via the image namesetting the table behavior for the images table under power pivot --> manage --> Advanced (e.g. Default Image: Content)opening power view and building article cards with article number and imageProblem: only a camera icon shows up in power view
Is there a solution with a desktop version?Can I use my Office 365 Pro account to make it work? How?Why is there no solution showing images in a pivot table?Link to Dropbox with power pivot files
I have several reports in a Power View Gallery. In Gallery view, most of the reports show the "Open New Excel Workbook", the "Create Power View Report", and the "Manage Data Refresh" buttons on the right side of the report list. Why would some reports not have these buttons available? In the attached image you can see one report with the buttons and one without the buttons.
I've imported a number of excel sheets into a Power Query Table. All seems to appear ok until I load the data. Of the 15k rows around 2k have a similar error where it cannot convert an integer to type string as below example
Expression.Error: We cannot convert the value 40 to type Text. Details: Value=40 Type=Type
The columns in question are all of integer type, I've looked through the M query and there is no conversion to string taking placeThe values where we don't get the error are also integers hence the intriguing question is why does the error occur on a subset and not the others. I suspect there is a limit to the number of errors also somewhere internally M query is converting the column to text for some reason.
Slow loading issue with an if statement. In the raw data the field [Location] is a text field e.g. 0010. I have a parameterised query that get a Location_Value from Excel and passes it to the PQ query using:
#"Filtered Rows1" = Table.SelectRows(#"Removed Other Columns", each ([SalesMode] = 0) and ([SalesType] = 0) and ([Location] = Location_Value))
This works fine if you chose a single location. However I wanted to be able to select all locations and text is horrible to work with so in PQ I used the change type function to change the location column into whole numbers. I changed excel to also pass a number as Location_Value. I was therefore surprised when the same query took 2.5 times longer to refresh????
My PQ now looks like this
#"Changed Type" = Table.TransformColumnTypes(#"Removed Other Columns",{{"Location", Int64.Type}}), #"Filtered Rows1" = Table.SelectRows(#"Changed Type", each ([SalesMode] = 0) and ([SalesType] = 0) and ([Location] = Location_Value))
I'm wondering if I need to do something to the ([Location] = Location_Value) bit as maybe it still thinks [Loation] is text and it is trying to compare it to a number. I st assumed the step above meant that [Location] was now a number, but maybe you still have wrap it with some kind of VALUES or TEXT function?

I have to generate rank like this in power pivot. How can I achieve it?
I have opened an account in [URL] and taken the 60 days trial for power bi pro. I've developed power pivot and generated power views in share point 2013. But, I'm new to Power BI desktop. I have created a report in power BI desktop and published to [URL]. Also, I have uploaded an excel file directly to [URL] and created the report from the workspace available there itself and pinned the report to dashboard also. Everything is fine till this. But, I need to refresh the file which I have uploaded. I have some dummy data in excel sheet.
ZipCode State ZipName
2345 AA AA 456 BB BB 6787 CC CC
This has been created as a table and then added to data model. So, power pivot has been created for the same. Then I have uploaded this file to [URL] site. But, I'm getting an error message while trying to schedule refresh for the same.
"You cannot schedule refresh for this dataset because it does not contain data model connections. You cannot schedule refresh on worksheet connections or linked tables. To schedule refresh the data must be loaded into the data model."
How can I create a data model connection? How can I schedule refresh for an excel file like this?
I'm a relative newcomer to Power View. I've been playing with charts and have been struggling to combine both line and bar on the same chart. It would appear this functionality is not available. Considering this is basic functionality when it comes to charting, how to achieve this....
I'm looking to replace text in a given column given a set of conditions in the other columns. Please see below the M query in the advance editor and in particular the bold text. Here I've created a new entry that would appear in the query applied steps window in the power query editor that I have called "Replace Values". The logic is if Data.Column4 column equals "London" then replace null values in Data.Column5 with London. However when I save the query below I get the error
Expression.Error: There is an unknown identifier. Did you use the [field] shorthand for a _[field] outside of an 'each' expression?
I plan to change the expression to test for multiple conditions however I need to get the basic expression working first. The other frustration i had with the "if" statement is it had to have an else even though I didn't require it, am i doing something wrong here?
I want to show on Power BI Dashboard a moving average - for example, I want to always show the last 30 measurement of body temperature but it looks like Power BI dashboard shows all measurements I have and compress them - which makes the dashboard ugly.
I tried to customize the X-axis properties but I dont know what I should change the default start/stop properties to (where the default property value is automatic).
1) Production data with column headers: Key, Facility, Line, Time, Output 2) Costs data with column headers: Key, Site, Cost Center, Time, Cost
The tables have a common key named obviously as Key. The data looks like this:
Key Facility Line Time Output Alpha
I would like to have two pivot tables which I can filter with ONE slicer based on the column Key. The first pivot table shows row labels Facility, Line and column labels Time. Value field is Output. The second pivot table shows row labels Site, Cost Center, and column lables Time. Value field is Cost.How can I do this with Power Pivot? I tried by linking both tables above to a table with unique Keys in PowerPivot and then creating a PivotTable where I would have used the Key from the Keys table.
I have a simple pivot table (screenshot below) that has two variables on it: one for entry year and another for 6 month time intervals. I have very simple DAX functions that count rows to determine the population N (denominator), the number of records in the time intervals (numerator) and the simple percent of those two numbers.
The problem that I am having is that the function for the population N is not overriding the time interval on the pivot table when I use an ALL function to do so. I use ALL in other very simple pivot tables to do the same thing and it works fine.
The formula for all three are below, but the one that is the issue is the population N formula. Why ALL would not work, any other way to override the time period variable on the pivot table.
Population N (denominator): =CALCULATE(COUNTROWS(analyticJudConsist),ALL(analyticJudConsist[CurrentTimeInCare1])) Records in time interval (numerator): =COUNTROWS(analyticJudConsist) Percent: =[countrows]/[denominatorCare]
I have simple pivot table (below screenshot with info redacted) that displays a population number ("N" below), this is the denominator, a cumulative numerator number (below "#") and a simple cumulative percent that just divides the numerator by the denominator. It cumulates from top to bottom. The numerator and percent are cumulative using the below functions. There are two problems with the numerator and percent:
1. When there is not a number for the numerator, there is no value displayed for both the numerator and the percent..There should be a zero displayed for both values. 2. When there has been a prior number for the numerator and percent (for a prior month interval) but there is no number for the numerator in the current month interval, the prior month number and percent are not displayed in the current month interval--see the 3rd yellow line, this should display "3" and "16.7%" from the second yellow line.Here is the formula for the numerator:
=CALCULATE(count(s1Perm1[entity_id]),FILTER(ALL(s1Perm1[ExitMonthCategory]),s1Perm1[ExitMonthCategory] <= MAX(s1Perm1[ExitMonthCategory]))) Here is the formula for the percent: =(CALCULATE(countrows(s1Perm1),FILTER(ALL(s1Perm1[ExitMonthCategory]),s1Perm1[ExitMonthCategory] <= MAX(s1Perm1[ExitMonthCategory]))))/(CALCULATE(COUNTROWS(s1Perm1),ALL(s1Perm1[Exit],s1Perm1[ExitMonthCategory])))
We are trying to build dashboards using Power BI desktop version with Power Pivot data model as a back end. To import the data to Power BI,we used Import ->Excel workbook contents option and successfully imported the model to Power BI .When I tried to refresh the Power BI,It's hitting the backend tables available in the power Pivot model. But my requirement is I need to refresh the Power BI from the power Pivot Datamodel(I'm expecting an option like Import from Power Pivot in Tableau).
One big reason why we have turned to Power BI for Office 365 is to share Power Pivot models with our senior executives who all use Macs.
While they have been able to successfully view the Power Pivot models and interact with the Slicers in Power BI, they have not been able to print the reports. We thought it was a Mac issue but it's happening on PCs too. There doesn’t seem to be a way to resize the report so that all columns print. So we then tried to click on the tiny button located in the bottom right corner that says “View Full-Size Workbook.” The file then opens up in Excel Online. Then when we click on the printer icon, we see the report but the slicer becomes invisible. When printing, all columns do show up however the slicer is invisible.
How to successfully print Power Pivot reports with slicers in Power BI?
I have data in my Powerpivot window which was generated by a sql query. This data includes a field named 'Cost' and every row shows a value for 'Cost' greater than zero. The problem is that when I display this data in the pivot table all entries for Cost display as $0. At first I thought that maybe Cost was set to a bogus data type (such as 'text) but it is set to ''Decimal Number' so that's not the problem.
What is happening and how do I fix it so that my pivot table reflects the values for 'Cost'?
I have a data table that contains budget and actual data by month. I use the data to create a pivot that shows actual results next to budgeted results. I need a column that shows that variance between those columns. I think my issue is that the "Type" field contains actual and Budget. I sum on "Type". I can't seem to create a sum since those items are in the same field or am I missing something?
How to get a list of values to actually display in correct order in either a slicer or when on an axis on a pivot table?
I currently have the below list and have tried to add a preceding numeric (ex. "1. <=0") or preceding blank space, neither of which is visually great. Is there another way?
I am using excel 2010 and creating pivot table from Power Pivot. I created a pivot table with department slicers. All is good, the problem I am having is whilst in an unfiltered position (ALL) of the slicers (departments) I get 200 pages, now when I click on a given department with say 10 pages, I still get the same 200 pages with the first 10 pages showing the data from the clicked department and 190 blank pages.
All I want is to get a WYSIWYG (What you see is what you get) of what is on the screen as my print, but I am getting extra blank pages right after the data. How do I resolve this.
Below are the steps I go thru to print
1. Select slicers in unfiltered position (ALL) 2. Select entire pivot table 3. Select Page layout and select print area. 4. Save 5. Click on Print Preview to preview the print 6. Click on a given department in the slicer and repeat item 5, but this gives me blank pages after the data.
Is it possible to generate automatic refresh of excel 2013 table which displays some table of a power pivot model on file open?? I dont want to use pivottable (which supports this ...)
I have a pivot table that connects to our data warehouse via a PowerPivot connection. The data contains a bunch of comment fields that are each between 250 and 500 characters. I've set the columns in this pivot table to have the 'Wrap Text' set to true so that the user experience is better, and they can view these comment fields more clearly.
However, whenever I refresh the data, the text wrapping un-sets itself. Interestingly, the 'Wrap Text' setting is still enabled, but I have to go and click it, then click it again to actually wrap the text. This is very burdensome on the user, and degrading the experience.
Any way to make this text wrapping stick so that I don't have to re-set it every time I refresh the data?
Is it possible to get difference between two dates - first one and last one per every group in table (records are sorted by ID)?
