Well I have a table with the headers of the customer ORDERS. Now, I need to create a portal with inside the customers that have a related order.
So my layout is based on ORDERS, and to populate correctly that portal, I believe that the way is to create a summary list field based on id_customer, create then a 2nd calc field that is = that list, and create on it the relationship with the customer table.
Isn't it a little bit tricky? Does anyone have a nice approach?
