The available stocks of raw material, semi-finished and finished material are important for the various production areas. Planned values (per month of year) are created at the level of valuation classes, in terms of the material stocks. The planned values are compared to the actual stock values. The evaluation makes it possible to compare actual and planned figures to the day, specifying the deviation. In parallel to this, data from earlier periods (previous month, 12 or 24 months) is displayed as a comparison.
