How can I cause Sonar to re-examine an entire file, not just the lines I changed?

I need a help regarding SonarCloud analysis. I want sonar to analyze a complete file not just the changed lines.
Can you suggest me how can I do it.

Hello @ah6557,

Your post lacks a lot of context. When analysing code, SonarCloud analyzes the whole files, but then separate the issues in 2 sets, issues on new code and issues on the whole code.

Please explain in which context you see SonarCloud not analyzing the whole files
