So, I am still crafting reports to use with commandreporter to get the data I want for a program I'm writing but I've hit a snag. Only Students seem to have a unique identifier that I can choose to export (UPN or Admission Number for example).
Contacts/Parents don't. How am I supposed to link parents to pupils without duplication when this is the case? I can't generate one of my own via combinations of other fields as *all* those fields can change at any time. Ideas?
