Display checked data in SM30 Evenet (Bfore saving data to database)

Dear all,

I wanted to create a popup when the user enterd the entries in SM30 and pushed the saving button. This POPUP is only a information for this user and not a creteria to save the data or not.

My question

1) Its is possible in this event to display a popup?

2) what kind of popup can I use ? I need something like ALV as POP

best regard
