HI Everyone，
I met some problem when customizing reports for equipment in OPPA CE, here're the questions.
First, How to group the equipment by higher class rather then the only base class, for example, Par. Horizontal Pump and Par. V-Inline Pump are now counted in two different groups, How can I make them show in one group called Pumps.
Second, how to enable the value in one column equals to the multiply of values in another two columns. For example, the Total Weight equals to Count*Dry Weight.
