The portal is the right way to go for this. The button that does the GTRR must be on the portal row. It will go to the proper related record.
Go to Related Record [ from table:SelfJoin; Using layout "Students" ]
Also if you want your portal to display all records instead, you can use the cartesian product 'X' operator instead of the '=' in your self join.
Thank you very much for this tip on displaying all. Works great!
But I still cannot get the GTRR function to work in this particular case.
I have tried many ways to relate this self-join with varying results, but never able to GTRR.
I just cannot seem to get this combination to work.
Any ideas or do I need to provide more information?
Thank you very much for your help.
Please state exactly the steps that you are doing. If you did it correctly, in browse mode, you should see each row having its own button.
