About the \begin{enumerate} list environment, when I use item, instead of having this in my pdf document
1.
2.
3.
4.
I would like to display the following
P1
P2
P3
P4
Where P is a single character. How can I do that please?

You can change \hsize to \linewidth inside multienumerate, so the environment is aware of the current value for the line width (the package uses \textwidth by default); the representation for the counter used can be changed ny redefining \labelenumi. Another option, if your inner items are naturally balanced would be to use three columns built, for example with the multicol package. The following example shows both alternatives:
\documentclass{article}
\usepackage{enumitem}
\usepackage{multienum}
\usepackage{multicol}
\begin{document}
\noindent Using \texttt{multienum}:
\begin{enumerate}
\item
\setlength\hsize{\linewidth}
\begin{multienumerate}
\setcounter{enumi}{0}
\renewcommand{\labelenumi}
{\addtocounter{enumi}{1}\alph{enumi}.}
\mitemxxx{Not}{Linear}{Not}
\end{multienumerate}
\end{enumerate}
\noindent Using \texttt{multicol}:
\begin{enumerate}
\item \begin{multicols}{3}
\begin{enumerate}
\item Not
\item Linear
\item Not
\end{enumerate}
\end{multicols}
\end{enumerate}
\end{document}
Perhaps the best option is to use the enumerate* environment from the enumitem package with the inline package option and to control the spacing between items using \hfill:
\documentclass{article}
\usepackage[inline]{enumitem}
\begin{document}
\noindent With \texttt{enumitem}:
\begin{enumerate}
\item
\begin{enumerate*}[itemjoin=\hfill]
\item Not
\item Linear
\item Not
\end{enumerate*}
\end{enumerate}
\end{document}
With the edit to the original question, a better option seems to be the use of a tabularx environment (from the tabularx package) of width equal to \linewidth and with automatic cell numbering:
\documentclass{article}
\usepackage{array}
\usepackage{tabularx}
\newcounter{row}
\renewcommand\therow{\alph{row}}
\begin{document}
\begin{enumerate}
\item
\begin{tabularx}{\linewidth}[t]{*{3}{>{\stepcounter{row}\makebox[1.8em][l]{(\therow)\hfill}}X}}
part 1 & part 2 & part 3\\
part 4 & part 5 & part 6\\
\end{tabularx}
\item
\setcounter{row}{0}
\begin{tabularx}{\linewidth}[t]{*{3}{>{\stepcounter{row}\makebox[1.8em][l]{(\therow)\hfill}}X}}
part 1 & part 2 & part 3\\
part 4 & part 5 & part 6\\
\end{tabularx}
\end{enumerate}
\end{document}
And, of course, if this structure is to be used several times, you can define a new environment to simplify the writting:
\documentclass{article}
\usepackage{array}
\usepackage{tabularx}
\newcounter{row}
\renewcommand\therow{\alph{row}}
\newenvironment{rowenum}
{\setcounter{row}{0}%
\par\noindent\tabularx{\linewidth}[t]
{*{3}{>{\stepcounter{row}\makebox[1.8em][l]{(\therow)\hfill}}X}}%
}
{\endtabularx}
\begin{document}
\begin{enumerate}
\item Question 1 preamble
\begin{rowenum}
part 1 & part 2 & part 3 \\
part 4 & part 5 & part 6 \\
\end{rowenum}
\item Question 2 preamble
\begin{rowenum}
part 1 & part 2 & part 3 \\
part 4 & part 5 & part 6 \\
\end{rowenum}
\end{enumerate}
\end{document}
If you want to resume the numbering after a modification
\documentclass[fontsize=12pt, paper=a4]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage{ngerman}
\begin{document}
\begin{enumerate}
\item bla \stepcounter{enumi}
\item[\theenumi--5.] bla bla \setcounter{enumi}{5}
\item bla bla bla
\end{enumerate}
\end{document}
Thanks to egreg and Mico for the correction/modification!

This can be easily done with
enumitemand itslabeloption. Since the letter P is to be followed by a arabic number, the labelP\arabic*is used.
