Overriding a preselected biblatex style, and suppressing unwanted BibTeX fields

Question

I am trying to suppress printing data related to article issue and month by using biblatex, but the code below does not work for citations generated by \mcite (or \mcitesupercite), although it does for simple citations generated by \cite.

\AtEveryBibitem{%  
\clearfield{issue}%  
\clearfield{month}%  
}  

Is there any simple way to allow that?

Answer 1

If you are using biblatex 2.0 and biber 1.0, try this:

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \pertype{article}
       \step[fieldset=issue, null]
       \step[fieldset=month, null]
    }
  }
}
