Enterprise level To collect all information concerning the material flow in the paper mill, induding e. g. quality parameters of the produced paper. The information is usually collected in a very rough time scale, i. e. reel based. The purpose is to derive figures which are required for commercial control of the mifl. 

Process level To collect quality and process data in quite high time resolution to be able to analyse and track process problems, to find the technical reasons for poor/excellent production, or to summarize the data in reports as needed by the enterprise levd systems.
