Troubleshooting

Problem	Frequent Cause	Solutions
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.
