General ⇒ \acro - Hyper reference undefined - but not everywhere

[TomWrite]

Hi Stefan,
thanks for the hint. I will dig into overleaf.com to see where I can properly export it.

However, in the meantime I think I found the "issue". I don't know how to replicate it here, but I try to explain it and maybe someone recognises it.

My document is structured in individual files. Therefore my documents looks like this:

Code: Select all

%\usepackage[pdfpagelabels]{hyperref} 
\usepackage[printonlyused]{acronym} %Abbreviations

\section{Hauptteil 1}

\include{sections/hauptteil_1/zusammenfassung_teil1}

\appendix
\section{Anhang Hauptteil 1}\label{secA1}

\include{sections/hauptteil_1/appendix1}
\end{document}

If I use for example \ac{ISG} in an earlier file, like allg_ausgangslage.tex, then it works like a charm. The warning note of the undefined ref disappears and the hyperref for the acronym is shown in the list of acronyms.
However, if I remove \ac{ISG} from the allg_ausgangslage.tex and move it to a later file, like sections/hauptteil_1/analyse, I have the same "problem" again. The warning note appears again and the entry in the list of acronyms is not a link anymore.

So apparently the warning depends on where the first usage of \ac{ISG} appears.

In both cases \ac{ISG} creates the correct entry in the text of the respective page.

Not sure if this makes sense. But I hope I could explain it a bit.
