    Hi jmg80525 

     

    Thank you for this information. Did you try to load the parameter? Based on my test, if I try to load the parameter, I have the same "UnknownError" when saving the dataflow. However if I don't load the parameter, I can save the dataflow successfully. Just keep the "Enable load" option unchecked as default and try saving again. 

     

    This is probably not an issue due to the following dataflow limitation from Dataflows considerations and limitations:  

    In Power BI dataflows, you can use parameters but you can't edit them unless you edit the entire dataflow. In this regard, parameters in dataflows behave similar to declared constants.

     

    Best Regards,

Hi jmg80525 

 

I cannot reproduce this error at my side. Sometimes this would be a temporary issue. Do you still have this error now when saving a dataflow that is connected to a folder?

If you still have this error, can you save a dataflow that is connected to a local file? 

If you create a dataflow connecting to the same folder in a shared capacity, will this error occur?

Do you have some computed tables in the dataflow by referencing some tables? 

 

In addition, with a PPU license you can submit a support ticket. Please refer to How to create a Fabric and Power BI Support ticket - Power BI | Microsoft Learn

 

Best Regards,
Jing
