Just use 'raise_application_error' to raise message from backend. Catch this message by on-error trigger. Then display.

But if I use 'raise_application_error' the flow will end there itself, and I want to get messages, as it happens in forms without breaking the flow.

I am looking for the same "A continue message service from backend to front end?”
As we do it in forms, like we can display the value of some variable in forms to pop up using message command I want the same for a backend variable values to be popped up in the front-end or if I give a message in the backend it should get displayed in the front-end

I hope no its clear. let me know if you have anymore queries.

"A continue message service from backend to front end?” or "displayiny text on demand/call" both are different things with different logics. from Backend 'insert into table'. from frontend use TIMER to fetch and display value.
If this logic is not satisfying you then please give more clearity. How you executing from backend?what is message it is text or error? How you want to show in forms?

Push the message into a package variable and when you return to the form it can see if the package variable contains anything. If it does, then it can 'message' it and then clear it.
