Sometime we needs to add new columns in Power BI whatever we have created the same in Database.
In order to do so follow the below steps.
1. Open Power BI report in Desktop.
2. Click on Home -> Edit Quires.
3. In Query Editor click on Home -> Refresh Preview
We will have tow options ( Refresh Preview & Refresh All). IF you wants to refresh only the selected table then clink on Refresh Preview and if you wants to refresh all tables in Data model then click on Refresh All. This step will bring all new columns in respective tables.
4. Then save and close.
Enjoy !!
