# MakeUppercase and chapter font

I'm using the \MakeUppercase command (from \textcase) (but also tried \MakeTextUppercase cos I thought the problem might be caused by the math-environment of the chapter number) and the \addtokomafont{chapter}{...} command to set up the Koma-script report class. My MWE is based on the following thread. Unfortunately, adding \MakeUppercase to \addtokomafont{chapter}{\normalsize\scshape} doesn't compile with the changed chapter format but it does without, does some one have an idea how to solve the problem?

\documentclass[
fontsize=12pt,
twoside,
a4paper,
parskip=half,
ngerman,
open=right
]
{scrreprt}

• I am pretty pretty sure that i have read that very same question earlier today, it even had a helpful answer. I bet the person who wrote the answer is not very happy to see his effort wasted by deleting the whole thread. Sep 9, 2015 at 17:31
• I wonder if there is a better way but one could patch \scr@makechapterhead and \scr@makeschapterhead Sep 9, 2015 at 20:36
• BTW: you're missing to load fontenc – is that on purpose? Also you load german instead of ngerman with babel which means you have old spelling instead of the new (no so new anymore) one. Sep 9, 2015 at 20:41
• Do you mind to explain to me what do you think is causing the error? It seems not to be the interaction of the chapter number (in math mode) and \MakeUppercase as I thought (cos even be editing this part I still get the same error message).

• @harryhaller if you want to notify someone ping them with a @ followed by the user name. The problem is that after the chapter font is inserted what follows isn't the corresponding heading directly but a whole bunch of internal commands. So \MakeTextUppercase (or whatever) acts on a lot more than just the heading. Sep 10, 2015 at 10:09

This is possible with KOMA-Script version 3.19 or newer. In version 3.19 the new commands \chapterlinesformat and \sectionlinesformat have been introduced. They are explained in the KOMA-Script documentation.

Here is a suggestion using these commands:

\documentclass[
fontsize=12pt,
twoside,
a4paper,
parskip=half,
ngerman,
open=right
]
{scrreprt}

\usepackage[english,german]{babel}
\usepackage[utf8]{inputenc}
\usepackage{color}
\usepackage{blindtext}
%\usepackage{showframe}

\DeclareMathAlphabet\EuRoman{U}{eur}{m}{n}
\SetMathAlphabet\EuRoman{bold}{U}{eur}{b}{n}
\newcommand{\eurom}{\EuRoman}

\usepackage{textcase}

\setkomafont{sectioning}{\rmfamily}
\setkomafont{caption}{\small}
\setkomafont{captionlabel}{\sffamily\bfseries\small}
\setkomafont{chapterentry}{\small\bfseries}
\setkomafont{chapter}{\normalsize}
\setkomafont{section}{\normalsize}
\setkomafont{subsection}{\normalsize}

\renewcommand\chapterlinesformat[3]{%

\renewcommand*{\sectionlinesformat}[4]{%
