I made a relations (1:n) between 2 tables. Not every element from fathers layer have connection with elements from child layer. The connection is made between 'Tipo de Estrutura' Field and 'Est' Field like shown below.
The relation is made correctly. My problem is with the elements that have no relation (Example 'Rocha'). When I open the 'identify feature' of 'Rocha' Element is shown a relationship table with no elements. It is possible to only show relation when exist or hide this connection?
