Hi Tammie and Heather,
For such cleanup / impact analysis, I invite you to use our Report of Report Details solution, which automatically documents your Workfront report configuration into an Excel spreadsheet that you can easily filter to assess the impact of renaming parameters and plan accordingly.
As per this screenshot, for each parameter (row) and filtered-selected report (column), each cross reference cell then shows WHERE a parameter is user (“generally”), and HOW a parameter is used on the report in either the Filter, View, Group By, or Sort (“specifically”).
Regards,
Doug
