How to perform a count for a column based on another two columns in one data item.
Let's say I have 3 data items Student,subject,section
I need to calculate distinct count for student who is taking particular subject from those many number of sections. But in our report we r showing calculated item having distinct combinations of student taking subject frome those sections. we r not populating these three dataitems (student,subject,section)
any ideas please
Thanks in advance
