Processing takes long when trying to edit a data source and then refreshing it
Thanks.
There might be different causes for it.
However note: The edit experience on a Data source is meant only for Data Preview and therefore any complex operations applied on the whole data is bound to take a long time. We recommend restricting the number of rows to around 100 (Choose Keep Rows -> Value 100) and then specify the transformations as necessary for the data source. Also ensure to remove the step Keep Rows from the list of steps on the right if you have this step defined. Save the datasource and all the data will be processed, hopefully faster than before.
If it doesn't help please work with your tenant admin to open a support ticket here: admin.powerplatform.microsoft.com/support
Thank you!
