What does Enable Source Control (EnableSCC) do in the experimental localization dashboard tool?

I’m unable to find any documentation or explanations for this option, and I’m concerned it may be influencing a problem ( [4.12.3] Localization Dashboard Can't Match Criteria for Packages - Programming & Scripting - Unreal Engine Forums ) I’m experiencing while working on a 4.12.3 project that’s been under development using Perforce for version control.
