|General error messages|
Error messages are often due to columns having been renamed in a preceding node and the current renaming process lacking reference.
|Have a look at the individual columns and check whether the variable is available in the left column - if necessary delete rows or select correct column name.|
|"An Item with the same key has already been added"||This can happen if two columns have the same name, typically after data merging.||Workaround: delete one of the two columns with the operation Delete columns and then proceed with renaming / reordering / deleting columns.|
