Hi,
I work with Power BI Desktop and Service and have began using DataFlows to extract data from Database. When I added a new column to the table in my database, the entity in dataflow starts giving error. The error stated that there were more columns than expected. This causes report failures.
Can anyone tell me how to solve this and update dataflow entity to include newly added column in source.
Any help appreciated
Thanks

Hi @Parimal_Patil ,
If the source of your dataflow changes (i.e. more/less columns), you can try this workaround:
You can validate all of this happens by reviewing the exported JSON file before valdiating and saving your dataflow and then viewing again after saving...you'll noticed that before the JSON did not having the new column and after, it will.
You can refer this similar issue about this in details: DataFlow Refresh Error
