Conditional Column in power query

[dayawan]

Hi Team,

In Power BI, calculated columns are easy to identify because they have a distinct icon. However, when I create conditional columns, I don’t see a clear way to distinguish them. Is there any method to identify which columns were created as conditional columns? I sometimes lose track of the ones I’ve added.

No, for others' files, you would have to inspect each query step in Applied Steps to find out which columns were added as conditional columns in case the step names were renamed. For you own queries, i'd suggest renaming those conditional Columns with certain flags so that you can identify them in a quick way later.

Hi @dayawan I'm assuming you're referring to a coniditional column created in the query editor. In Power BI, a custom column created in the Power Query editor exists only at the query stage and is treated like any other column once the table is loaded into the data model. The model has no built-in way to identify it as custom, so it cannot distinguish between columns from the original source and those added or transformed in Power Query, meaning all columns are effectively equal in the model and any “custom” identity is lost unless manually documented or flagged (adding an indentifier in the column name).

Hi @dayawan,

There is no easy way to identify the conditional column created in Power Query as Power BI doesn't assign a logo to it, But you can rename the applied step in Power Query as added conditional [column name], or you can prefix column something like Cndsnl_[column name], so that you can easily identify that this is a conditional column.
