Tidy up Power BI models with the Power BI Cleaner tool

Edit: I am retiring support for this tool for now, as you can find an alternative here: Measure Killer | Brunner BI.
Please feel free to use this tool as it is, but I am not fixing any bugs or provide further help for it. Power BI Cleaner is now published with ‘Power BI Sidetools’ by Didier Terrien: https://github.com/didierterrien/Power-BI-Sidetools/releases Didier may provide help in some cases. Please post issues here:  https://github.com/didierterrien/Power-BI-Sidetools/issues

Edit 27th June 2021: There is a complete new version of this tool that has all the bugfixes and enhancements here: Power BI Cleaner – The BIccountant

The VertiPaq-Analyzer tool is one of the great community tools that I really cannot live without. It gives me a great overview of all elements in my model and identifies potential performance problems by showing the storage requirements of each column. So when seeing expensive columns, the first question that arises is: “Do I really need this column or could I delete it?”. Luckily, this can now be answered with my new Power BI Cleaner tool. This tool shows the usage of all columns (and measures) within the tables of the VertiPaq Analyzer.

Power BI Cleaner shows unused columns in the VertiPaq-tables

Power BI Cleaner tool

So whenever there is no entry in the column “Where Used” you can go ahead and eliminate the column (or measure) from the model. Well – with two exception actually: Fields used in the definition of incremental load policies are currently not identified as well as used fields in calculation groups. So make sure to consider this before running wild 😉

In the table “Measures” you can spot which measures might not be used:

Identify unused measures with Power BI Cleaner Tool

And as a general recommendation: Always make sure to have your old version still in place and create a new version for your cleaned up file, just in case.

To learn more about the used elements, you can drill through to detail pages “Where Used Direct” and “Where used Indirect”:

Drill through to detail pages

“Where Used Direct” will show where the elements are directly used in:

Analyse directly used elements

And the next page “Where Used Indirect” will show elements that are using the selection indirectly at a later stage as well:

Elements that are indirectly used at a later stage

Please note that the drill through pages will only return values for columns and measures that have been used or referenced by used items (directly or indirectly) . So if a column or measure has been used in another column or measure this will not be shown as long as those elements haven’t been used anywhere in the report. This is intentional and reflects the purpose of the tool to be used as a cleanup-helper and not as a documentation tool.

What’s (not) covered

The areas covered for usage detection are the following:

  • Calculated columns
  • Measures
  • Relationships
  • Filters (on visual, page, report and drillthrough-level)
  • Visuals
  • Groups
  • Roles
  • Conditional formatting

And again – NOT covered are:

  • Incremental load policies

Please let me know if there are areas that I’ve missed and I’ll see if I can include them as well.

Further limitations

  • Columns that are only referenced by their name (without the preceding table name) will NOT be detected.
  • False positives will be generated for measures that have the same name than column names: Unused measures will be flagged as  used, if their column counterparts are used!
  • Some custom visuals produce bad metadata which can lead to errors as well. The Network Navigator for example, renames the input table to “Table1” in the metadata. These fields will not be discoverable through this tool.
  • Column and measure names including brackets “()” will currently not be picked up (this limitation might be lifted in future updates)
  • There is a problem with the automatic escaping of Text boxes. So special characters in there might cause problems.
  • It doesn’t work on models that are using live connections

How to use

  1. Retrieve vpax-file with DAX-Studio and paste path to vpax-file into parameter “FilePathVPAX”. ( ! This is a preview-feature that you have to enable like described here: https://www.sqlbi.com/blog/marco/2019/09/15/vertipaq-analyzer-2-0-preview-1/ )
  2. Transform pbix to pbit and paste path for pbit into parameter “FilePathPBIT” (This facilitates showing of “WhereUsed”-column in page “Tables”)
  3. Ignore Privacy Levels (File -> Options and Settings -> Options -> Current File -> Privacy -> Privacy Levels -> check “Ignore the Privacy Levels….”)
  4. Refresh All

Or check out this video for a detailed walkthrough:

 

How does it work

The tool uses the library and functions of the VertiPaq Analyzer and many metadata parsing algorithms of my Power BI Comparer tool. After all I want to thank Marco Russo for the support and confirmation that it is totally OK to adopt their open sourced solutions to other tools.

All the logic of this solution sits in the Power Queries. So do you want to know how this all works? Then just open the query editor and study the queries.

Download file: As mentioned above, this article is outdated, so please use the version from the latest blog here: Power BI Cleaner Gen2 now covers Analysis Services Models as well (thebiccountant.com)

Troubleshooting: If the file doesn’t work for you despite checking all prerequisites and limitations, please send me your pbit and vpax files so I can examine further. (info at thebiccountant.com)

Enjoy and stay queryious 😉

  1. Tried to use the PBI Cleaner file but am getting errors when trying to refresh, multiple queries are giving errors with a [Source] column, tried to step through the queries to fix but struggling to tell what should be setup to fix in some cases. Can you please advise? Tx

  2. Thanks so much for sharing this project – it looks extremely useful.

    I tried it out on a file just now (that I need to tidy up), and first struck the same error as Chris (ref earlier comment). While the actual error was avoided using the v2 version, the report then doesnt show any results for Where Used = Visuals, Relationships, DAX Expressions, possibly others. All I see in Where Used is columns and hierarchies.

    As I described in an earlier comment, my query: UsedFields1 is showing an error at step: _GetRoles –

    Expression.Error: The field ‘roles’ of the record wasn’t found.

    I also noticed my query: UsedFields2 is showing an error at step: Result –

    Expression.Error: We cannot apply field access to the type Null.

    I tried deleting one unused Custom Visual – the report still uses Bullet Chart by OKViz which is up-to-date.

    I hope that info is useful. I can share the pbit and vpax files if that helps. I’m very keen to help get this working.

    Thanks again, Mike

  3. This is a great addition to vertipaq analyzer. It’ll remove the manual effort of finding references, especially within visuals.
    Will this be integrated into DAX Studio?
    Will there be any effort to detect columns without a table name?

    Reply

    • Hi Jon,
      thanks for the feedback.
      There will be no integration with DAX-Studio, as the data for the visuals isn’t included in any DMV.
      I could possibly create a version where detecting column names without the table name is an option. But as you can use the same column name in multiple tables, this would create false positives for those cases.
      So this would require additional documentation to highlight that risk. Let me see when I can manage that.

  4. Imke,

    I have 3 measures

    [Total Sales]
    [PY Sales]
    [% YOY Sales] =DIVIDE([TotalSales]-[PY Sales],[PY Sales])

    On the measures tab for [PY Sales] “WhereUsed” is empty.

    I don’t think this is intentional, or is it?

    Reply

    • Hi Frank,
      hast [% YOY Sales] been used anywhere in the report?

      [PY Sales] should only be shown in the “Where Used” if it has been used somewhere in the report. Directly or indirectly.
      So if [% YOY Sales] hasn’t been used anywhere in the report the measures that define it also shouldn’t show up.

      Otherwise: I have a new version with some bugfixes that you might want to try. Just give a me a shout please.

  5. Hi Imke,

    This tool is great but I have the same problem as Frank Tonsen.
    I can assure that [% YOY Sales] is used in my PowerBi but I get still no use for [Total Sales] & [PY Sales]. I would like to test this updated version you mentioned.

    Reply

      • Hi Imke
        I’ve tested the new version and the Problem still persists, but I can tell you that it is another Problem than I thought. The real problem is, that some measures and columns are not detected as used. Therefore the indirect used measures are also not detected.
        At the moment I cannot tell you anything these measures and columns have in common. The problem seems to appear completely random.

        Nevertheless is your tool very helpful, but I have to be very carefully before deleting anything.

I’m using measures to create dynamic card titles, and where I’ve used conditional formatting of a card’s title to directly reference a measure, that measure doesn’t get reported as being used.

  14. Hi Imke! Thanks for providing this tool. It looks very promising. However I seem to have several measures that are reported as not used (column “Used In” in the Measures report page is empty for the measure) although I indeed see that they are used in a visual.

  15. Hi Imke, I am working with version (V7) and spotted some issues with “Where used” column.
    It shows blanks where in fact a column was used in a table visual or another one as a visual filter. In a first case the “Merge Queries” step in “Filed Usage” query retrieves null values when the columns used in join does not precisely match each other.

  18. Hey Imke, what a great work . I’m starting to useit and have already removed the unnecessary fields for some powerBI applications . The content is much completer then powerBI helper from Radacad. The only issue I’m facing is that the update of the report is very slow ( 30 – 45 min ) and in query editor it is very very slow to make changes if necessary. Did you ever had the same issue ? I’m running it on laptop with 16 gb of memory .

    Reply

    • Hi Alain,
      make sure that background refresh is disabled (see first point here: https://www.thebiccountant.com/speedperformance-aspects/ )
      Otherwise: These queries take quite some time to refresh, because there is a lot to be done. (As you have recognized, it covers areas no other tool is doing currently).
      But I haven’t had a workbook where the refresh would take that long.
      How many measures do you have in there? And how many visuals? (Roughly)

  19. Hi Imke,

    Thank you for sharing the tool and it is super useful for data cleansing!

    I have a question on how to use your tool when connecting to “PowerBI dataset”.

    The setup of my PowerBI is as follow:
    – PowerBI model – 1 file with all the tables linked to SQL Server (eg. Model.pbix)
    – PowerBI reports – 10 files connecting to the same PowerBI model (ie. Model.pbix) by using “PowerBI dataset” (eg. ReportA.pbix, ReportB.pbix, ReportC.pbix…..etc)

    I was trying to convert one of report to PBIT file and also convert the PowerBI model to VPAX file like this:
    -> Model.pbix ==> converted to Model.vpax
    -> ReportA.pbix ==> converted to ReportA.pbit

    Then I used your tool to import the above 2 files and hit refresh, but the operation was failed and it says some refresh errors about “loading blocked by failures with other queries”. I am not sure if the tool can still be used if I split the model and reports in separate files?

    I also tried to convert the PowerBI model to PBIT file and and also convert the same PowerBI model file to VPAX and it was successful (it took almost 5 hours to complete the full refresh):
    -> Model.pbix ==> converted to Model.vpax
    -> Model.pbix ==> converted to Model.pbit

    Based on my settings with “PowerBI dataset”, am I allow to use your tool for analyzing my reports?
    Thank you!

    Best regards,
    Emily

    • Hello Emily,

  20. Hi Imke I have found the issue with my problem “cannot convert null to text”. The issue occur when the dataset contains a Role in RLS without any condition. The table for roles will fail for that row with the error. I have added a replace error in the middle but this might help you reproduce the error to build a even better script 😉

  22. Hi Imke. I’m using your Cleaner tool. Really works well. Thanks a lot for this! But I do have a question.
    If I’m using column [COL1] in Power Query (so not DAX) to create another column [COL2] in the table and I don’t use the first column [COL1] anymore in the report, will it be reported as “not used”? Will the PowerQuery still be working ok if I remove [COL1]? Or does it depend on when I do that?

    Thanks a lot!

  35. For the folks hitting the refresh error “The column ‘Value’ of the table wasn’t found”, Cha on our team found one trigger for this is if your source PBIX file has no Page-level filters on any page. A workaround that got a successful refresh of Power BI Cleaner was to add a Page-level filter to our source PBIX file.

    We’ve shared our files with Imke and she is looking at a fix.

    Reply

    • Hi Mike, thank you for your interest. In my case the source PBIX has a page-level filter at the page called ‘Tables’. I set WhereUsed[Details] filter on the rest of them and still hitting the error related to the colum [Value].

      Reply

      • Hi Thiago, did you apply the page-level filter on your original PBIX file, not the Cleaner file?
        1. Original / Source PBIX file – We edited our source PBIX file with a page-level filter first, then ran the vpax and saved the pbit file afterwards.
        2. Cleaner File – We used these 2 new files as input to the parameters, before hitting the refresh button.
        Everything seemed fine on our end.

    The column ‘Value’ of the table wasn’t found. Same error for Measures List, FieldUsageDetails & WhereUsed.

    Any ideas what went wrong and how to fix it?

  45. Hi Imke, great tool!
    Small bug report: if you have RLS roles without any filters the AllFields table that calls fnAllTextBetweenDelimiters. Worked great after I deleted the roles.

    I’ve also noticed if a field is used only as a Visual Level filter it’s not marked on “Where Used”

    Thanks!

    This is great work on your part! Unfortunately I cannot get the tool to work with Power BI. It seems to be a file path problem as there is an error in power query. Excel.CurrentWorkbook(){[Name=”pbitPath”]}[Content]{0}[Column1].
    Should the power BI version be looking for an Excel file?
    When I try to ignore privacy levels the file goes into an endless loop asking for the privacy levels again and again.

    I am using V12_SimplePBIX.pbit.
    Help please.

    Best regards

    Tony

    I have tried the file you suggest with Power BI and still receive the same error. The tool is still looking for a non existent Excel file. Excel.CurrentWorkbook(){[Name=”pbitPath”]}[Content]{0}[Column1].and this shows as an error in PQ.

    I downloaded the new Power BI version and the path problem is fixed. However after entering the 2 initial parameters the native query popup appears twice so I clicked run each time. the refresh starts to run and I am NOT asked for credentials or to ignore privacy levels. The query then crashes with the following errors:

    AllFieldsUsed
    Query ‘DMV_Columns’ (step ‘Inserted Merged Column’) references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.

    DistinctFields_Used
    Query ‘DMV_Columns’ (step ‘Inserted Merged Column’) references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.

    Thank you for your help

    Tony

    • Hi Tony,
      sorry for the inconvenience.
      I’ve included a passage in the blogpost now on how to ignore privacy levels through the menu if the pop up doesn’t appear (any more).
      Cheers, Imke

    I was able to resolve the privacy levels issue using options and settings, however I now get the following errors.
    AllFields_Used
    The specified distinct criteria is invalid.
    DistinctFields
    The specified distinct criteria is invalid.

    • Sorry, yes – will fix that in the next update.
      But you can drag it from the fields section yourself until then.

  52. Can this tool determine where columns/measures are used if the source is a shared dataset? We have many reports using data tables in a shared dataset and are struggling to identify if a measure is being used outside of the PBIX that contains the data model.
