The calculation dialog boxes comprise the essence of the Calculation module. The values that you enter in these dialog boxes together with the data in the process data sheets serve as the basis of the calculations displayed on the screen. Calculation item reports provide information that is more comprehensive.
When you open a Calculation Item window and some of the process data values are not filled in, you can select Highlight Process Data on the Options menu to highlight all the fields that you must fill in to carry out the calculation.
