The model "Advanced Table Display and Management" is mostly used to display a range of records. If you want to group: the problem is you have completely rebuild this model because the "Advanced Find" has to replaced by "Database Query" (with all problems of sorting etc.) or create a view in the database.
Is it an idea to add an element <Group By> and give a sum of all numeric fields or better by specifying this fields?
Or is there an option to create a module which created the sql-code for <From>, <To>, <Start From> etc. so we can replace the "Advanced Find" by "Database Query"?
