    Hi tomq04,

    Could you please use import mode to upload some records of data from Redshift to Power BI Desktop, then check if the issue persists?

    Thanks,

Hi tomq04，

Could you please post sample data of your table? In Query Editor of Power BI Desktop, you can add a custom column using the following formula. You can view the example in the screenshot below.

[DateColumn]-#duration(0,8,0,0)

 

Thanks,
Lydia Zhang

That did work, but it knocks us out of direct query mode.  I'll see if that is acceptable for our use case.

      Hi tomq04,

      Do you use import or DirectQuery mode to connect to Redshift?

      Thanks,

        We are using direct query, the table we are working with is >15mm records.
