Can you post a sample file?
Exporting portal data from context of the parent record is problematic. It may not even be possible to get all of the info you desire from that context.
You should go to table of the portal/child records and export from there with records sorted by the parent record for grouping and summarizing, even for things such as name.
It is much simpler and safer to export from a child record and include parent table info than to export from the parent and hope to capture non-summarized child data.
Thanks for the suggestions. I'll give these a try!
Was trying to figure out a way, but the data is FERPA protected, since it relates to financial aid recipients.
