Sorry but Crystal doesn't work that way. Crystal uses a pre-defined data object to display the data in a specified format.
If you pass a different data object then it will give you errors that it cannot locate column xyz.
Either;
a) Always pass the same number of columns & use some type of flag in the data to tell Crystal what columns to show. This is complicated because you would also need to set the position of the elements
b) Create individual reports for each scenario
c) Change the format of your Report

I would personally go with Option C. Group the Subjects by Student and then show the Subjects, Hours, Results etc in a table below each Student

Kind Regards
