KOMA script: Appendix sections A1.1, A1.2, … A2.1 and uppercase TOC chapter entries

appendixkoma-scripttable of contentsuppercasexetex

I use xelatex with KOMA script class scrreprt.
Now I have to number my thesis appendices as sections A1.1, A1.2 and subsections A1.1.1, and so on. Chapter entries in the TOC including chapter APPENDICES should be set uppercase.

Therefore, I redefined the \thesection and \thesubsection. The hyperref option hypertexnames=false makes sure that the links are linked correctly.
But now I want the TOC entries A1.1, … aligned with the normal sections and subsections numbers like:

 1.1 Section
     1.1.1 Subsection
A1.1 Appendix Section
    A1.1.1 Appendix Subsection

Setting the main font Verdana with fontspec additionally leads to reduced spacing between A1.1 and the corresponding TOC entry:

Reduced spacing of section and subsection entries in TOC

This might by caused by not defining A as an appedix prefix.

Further, I tried to make the TOC chapter entries uppercase with:

\addtokomafont{chapterentry}{\MakeUppercase}

But this produces error messages for the .toc file. Somehow this works fine for chapter titles in the text itself and also \nameref chapter is not uppercase as intended.

I hope anyone can help me with the appendix entry alignment and the uppercase chapter entry. Thank you in advance!

Here is my MWE:

Best Answer

I would simply use the \appendix command, and set the uppercase through the tocentry command, adding a complex command with argument like \MakeUppercase to the font commands is bound to break in this place, as the argument contains the link commands.
