Power Query in Power BI allows you to perform a series of steps to transform your data. One of the steps amongst this is to keep duplicate records.
Keep Duplicate Records In Power Query
We generally take out duplicate lines but if we need to keep and check what the duplicates are, Power Query allows us to do that. Suppose you have a set of data as shown in below image. You can see that the marked ones are duplicate values, let’s keep them.
Step 1: Go to Power Query Editor from Power BI Desktop
Get Data > Excel file > Load > Excel Data > Home > Edit Queries
Step 2: Keep the duplicate rows in Power Query Editor
Go to Home > Keep Rows button > Keep Duplicates option
Step 3: Close & Apply Changes
Click on Close & Apply option from the Home tab and this will apply all the pending changes on your data. When you open the file again, it will be saved as it is.
