Fields in use are blocking the movement of columns to files
I have replaced and added some columns in a dimension on which a view is based.
I understand that the replaced or deleted columns must be removed from any reports or replaced with active columns from the dimension.
However, I currently have three columns which, as far as I know, are not used in any report but still give an error when I try to move them from one file to another in the view builder.
The error that is given says that it is impossible to move these columns because they are used in a report. Therefore I want to check my reports' used columns again.
Is there a quick way to see which views are used by reports and which columns are used by reports? An SQL-code, if it is availible, would be perfect.
