Now You may see details about every order, order request and instance for which this order created in "Order details"
It is not possible i click through every order to check the order (rental) if i search for a specific rental (order). I don't have a field that the order refers to, except the etinity content id of the row.
At least it should have a name of the person who rented the vehicle and the rental start and rental end. And this should be sortable as well.
I hope you understand that the order table is insufficient for rental purposes.
I have created an excellent overview for all rentals with help of CCK Custom SQL Entity and show all instances layout in the frontend. But unfortunately it is not editable.
