How to find data sources ?

Hello,

 

We have some existing Power BI reports, and we want to find which are their data sources. First we tried to find them through https://app.powerbi.com, but it seemed that it was not possible (really it's impossible ??). Then we download the .PBIX file from Datasets, and opened it with Desktop. We picked the main query "Data input",  and in Query Editor > Applied Steps > Navigation, we saw a list of EXCEL files, but which one ? or ones ?

 

Thanks for your help

 

The first rows in Advanced Editor :

 

let
    Source = SharePoint.Contents("Company SharePoint root URL", [ApiVersion = 15]),
    #"Shared Documents" = Source{[Name="Shared Documents"]}[Content],
    PowerBI = #"Shared Documents"{[Name="PowerBI"]}[Content],
    #"Data Input" = PowerBI{[Name="Data Input"]}[Content],
    #"Filtered Hidden Files1" = Table.SelectRows(#"Data Input", each [Attributes]?[Hidden]? <> true),
    #"Invoke Custom Function1" = Table.AddColumn(#"Filtered Hidden Files1", "Transform File from Query1", each #"Transform File from Query1"([Content])),
    #"Removed Other Columns1" = Table.SelectColumns(#"Invoke Custom Function1", {"Transform File from Query1"}),
    #"Expanded Table Column1" = Table.ExpandTableColumn(#"Removed Other Columns1", "Transform File from Query1", Table.ColumnNames(#"Transform File from Query1"(#"Sample File"))),
    #"Changed Type" = Table.TransformColumnTypes(#"Expanded Table Column1",{"All columns"}),

Hi @hittony

 

Once you have the PBIX open, click on Edit Queries and then data source settings

This will then show you all the data sources in your PBIX file.

Hi there

You might be able to use the Vertipaq Analyzer to do this, which will show you the size of your tables and the associated columns.

I am not sure of any other way to get out the requirements you need. I know that the above will show you the columns and tables, but it will not show you the source files unfortunately.

hi @GilbertQ

 

Thanks for your advice, but "Data source settings" can only show the folder where are the source files. I would like to search for more accurate information, like which column corresponds to which column or to which caluclation from which source file.
