I'm using, lyx 2.0.2, how can I add the Subsubsection in a document with a report class to the TOC, I tried the solution provided in this Question but didn't work for me, it generated no errors but no Subsubsection is added to the TOC.
Now I have a couple of section* I added those with this:
\addcontentsline{toc}{section}{Conclusion}

\addcontentsline{toc}{subsubsection}{subsubsection label}
