Dataflow duplicate data after refresh

Hi Everyone,

 

I'm using dataflow connected with Azure Data Lake Storage Gen 2, and load data into Azure SQL DataWarehouse.

After refresh. Data in ADLS is duplicated into a new snapshot without deleting old snapshots.

Even when I deleted Dataflow, data remained the same in ADLS.

 

How can I delete old snapshots? or How to query only the newest snapshot?

 

Thanks & Best Regards

Hi! I am experiencing a similar issue where my dataflow data is duplicated.  It was fine on 10/21/22.  Today, the numbers are doubled after I refreshed the dataflow and the PBI report that uses it as data source.  Did you find a solution to your issue?

Hi there

Are you generating the dataflow from the Power BI Service?

Hi @GilbertQ ,

 

Yes I am

I am not sure why it is duplicating the dataset.

I would suggest opening a Support Case for them to investigate.
