I believe that there is a limit to the number of files that Power BI can retrieve from SharePoint. When retrieving from SharePoint, Power BI retrieves from the root folder and extracts all files from the root folder and its sub-folders, without hierarchy. My company has many subfolders in our SharePoint directory, with many files in it. When querying, I notice that many files are missing when the files are listed in the query editor. I feel that the missing files are due to the large number of files that we have in this particular library. Is there a known file limit for SharePoint?
