The thing with the response based transaction is that you have one first request-based transaction (Detected or Manually added), and from this transaction only you can create response based transactions. No automation here.
Means that you have By example: Login (As request based Transaction), and from there (once promoted), you can create 2 new response based transactions manually, the one identifying login failed because there is a error message showing up , and one successful login.
That's how it works.
Note - do no disable the request based transaction. If you do that, no response based transaction can be found.
