Is there any way to to determine if a field is used in a Workflow, Saved Search or Report, without having to dig through them and look for that field. I have a requests from from a Director to determine where a field on the item record is used, as they want to change the name and the data type. I would imagine there is a paid solution, but I was hoping for a free solution.

Might want to see if Flashlight by Strongpoint would meet your needs. Used to be $$ but is now free.

I have being in your scenario before. I use SDF for that. To be clear, I don't use SDF to do development. But I setup a SDF project in order to download all the customizations: custom searches, workflows, forms, templates, custom fields, custom records, scripts, etc. All the definitions are in XML format (except scripts) Then I search in the folder for the field internal name. It appears in SuiteScripts, custom forms, workflows, etc.

I do keep a production SDF download and the Search for across all files/objects/etc. in WebStorm has saved me hours of "oh where, oh where can my little field be?"
