Data different in data view than in Power Query and source

Hi,

 

For some reason my data is changing between Power Query and data view.  My source file is a simple Excel table.  I import this into Power Query without issue and the data looks exactly the same.  However when I view the data in Data view in Power BI the data has changed from a certain record forward.  I have deleted the data source and then re-imported, refreshed, cleared the cache and nothing is helping.  Why is Power BI doing this????

I have found the problem was due to rounding of milliseconds in power bi.  I updated my source Excel file to round to the nearest 15 minute block and it resolved the issue.

Please be aware, that the data might simply be sorted differently, as the sort order from the preview in the query editor will not necessarly be kept in the data model. So make sure to compare same rows here.
