I would like to know how can I get the suggestion when I do a \cite in Emacs-AUCTeX. The minibuffer tells me when I do C-c [ that:
No valid bibliography in this document, and no default available
So how can I set this default? I have a separated file with my bibtex references that is called by a master document, and I want the suggestion for any of the other files included.
The variable reftex-default-bibliography is what defines the default bibliography to use. I don't do much with mult-file documents, do you have reftex-plug-into-AUCTeX turned on?
