self-relationship case

[Ugo DI LUCA]

I want to be able to see duplicates of same product in a unique invoice. I tried making a calc text Product_ID&Invoice_ID (both txt), and use it in a selfrealtionship in my line items, but showing the result through a portal, it doesn't come to anything. What am I doing wrong ?

It should be working. Need make sure everything is set up right, like you have fields in the portal.

Shoul have edited this. Solved. Basic bad portal relationship. Lost 2 hours on this. I had sweared to not do this again. But I did it ?

Thanks anyway
