Alternative Flow in Alternative Use Case Flow can?

Question

I would like to know if I can have an alternate flow within an alternate flow in a use case. Type A1 alternate flow which has A2:

A1: O usuário clicou em Excluir
1 - O sistema solicita aprovação
2 - O usuário confirma (A2) (Aqui tem o alternativo do usuário clicar em "não" )
3 - O sistema exclui 
4 - O sistema imprime a mensagem "excluído com sucesso"

A2. O usuário clicou em Não
1 - O sistema retorna ao fluxo principal.

That’s right?

Answer 1

Yes, there is no problem having an alternate flow within another alternate flow.

The way the UC is described, depends on the company’s culture. For example I described this way in my TCC, the teacher approved. However, when I applied to my previous company, I used it as follows:

A1: User clicked Delete 1 - The system requires approval; 2 - The user confirms; 2.1 - If the user clicks no, the system returns to the stream where it was called; 3 - The system excludes; 4 - The system prints the message "deleted successfully".

In the company that I am now, we are describing in the same way as you, an alternative flow to the confirmation of the exclusion.
