Date format gone on relations connect

why Date format gone on relations connect

 

 

firstly i thought is happens because of date/time formats, and always spliting date/time to date and time, but now this trick stops working.

 

 

 

why this happens and how to fix?

    Hi Digger ,

     

    The flag with a calendar style indicates the date hierarchy.

    With no relationship, both two date columns have a date hierarchy.

    After the one-to-many relationship is established, the daily hierarchy of the main table will disappear.

     

    This is because Power BI has a feature called auto date/time. 

    When the option is enabled, Power BI Desktop creates a hidden auto date/time table for each date column, providing all of the following conditions are true:

    • The table storage mode is Import
    • The column data type is date or date/time
    • The column isn't the "many" side of a model relationship

    More details you can refer to

    Auto date/time in Power BI Desktop - Power BI | Microsoft Docs

  • Digger , when you join a table with date of date table, You might see this behavior. But Check in column tools , it should still be date, you might not get date hierarchy.

     

    You can add new date column

    date_start1 =[Date_start]
