I have used a set analysis in multiple sheets.
One of the parameters (LFL_flag) has changed its name (LFL_flag_weekly).
Is there an easy way to search through the whole app and see in what sheets and objects my parameter has to be updated with a new name.
There is a search/replace feature in data load editor.
You can check the search in all section, and it will be done in every section of code. At the left pane you can see the occurences of searched expression.
However you can search/replace only one row per action.
I think your best call is to use the API to export this some way. I don't know specifically how to do it, but if you read here you can see people have tried to do something similar before.
