Hi RGI,

 

How did you create dataflow entity query? Can you please share more about these?
BTW, current dataflow seems not support custom functions and advanced operations in queries.

These are the steps I take:

 

Choose the workspace

Click Create

Click Dataflow

Click Add New Entities

Click Teradata database

Enter server, gateway and authentication details

Click Next

    HI RGI,

     

    Did this issue only appears on teradata datasource? Have you use same authorization mode and corresponded credentials on it?


    In addition, you can also try to store this datasource as CDS-A entity, then get data from that entity if it works.

      We only have a problem with Teradata (on-premise). MSSQL (on-premise) data sources are fine. We can connect to several MSSQL servers through the gateway, but not to Teradata.

      Credentials are correct. We've checked and double-checked several times.

       

      We have not tried CDS-A. I wanted to keep it simple - if possible doing everything via the PowerBI framework.

      Initially I just want to know if this is a bug, and if so when/if it will be fixed.

        HI RGI,

         

        I try to search for similar issue on Internet and find one similar issue. It seems like operation timeout so power bi cancel to create data flow entities.

         

        Can you please refer to suggestion to reduce your data amount and try again?
