where to find a renamed Power BI column's data source original column name

[Anonymous]

Say you rename a column in Power BI, is there any way afterwards you or others can find out the original column name, which is the underlined column name.

right, i understand. the best you can do then is to perhaps take a copy of all the column headers, delete the change step, and then compare the headers to find the old and new values.

should show up as a change step in the query editor unless you alter it in say the underlying SQL, then it would be untraceable.

@samdthompson I do see the name changed step but I can not see the details of the name change?

@samdthompson If you hover your mouse over the field you will see the original table and field name.

@samdthompson Had an another look. The column name mapping can be found in the advance editor of the Edit query section.

Hey thanks for the update. Always good to find the proper way of doing stuff after working out the hard way.
