Update column value without creating new column
Hi Team,
I am new to Power BI and i would like to know the best possible solution for below condition:
I would like to update column value (data source is sharepoint custom list). For example, in SQL query I would do something like this:
update table1
set col1= "OOF"
where col2 = "Admin"
Thank you in advance.
Hello, Anonymous
Power Query
Enter in your query, click in the FX icon near the formula bar and insert this code:
= Table.ReplaceValue( #"PreviousStep" ,each [col1],each if Text.Contains([col2], "Admin") then "OOF" else [col1],Replacer.ReplaceValue,{"col1"})
Change the name of the step in red and you are ready to go.

Anonymous unfortunately you cannot update existing column but you can add new conditional column either using Power Query or DAX, if you use Power Query, you can rename the old one, add new one with the original name and then remove the old one, so one it is loaded in the model, you will see new column with original name with updated value. Hope it is helpful.
I'm looking to do the same. Any help is greatly appreciated.
