The "Development" menu holds one entry: - "Query Tool": opens [[Invantive Query Tool/Invantive Query Tool|Invantive Query Tool]] on the connection which is open. The Query Tool reads the same [[Business Vocabulary|seventeen views]] the screens read, next to everything else the underlying platform driver offers. It is the way to answer a question no screen answers: a total per period, a comparison between two companies, a selection which no filter expresses. The entry appears only when the Query Tool is licensed and authorised. See [[Open the Query Tool]].
