    Hi,

    Based on user inputs it will trigger the PBO.

    Consider this Example.

    We have two Screens.

    First trigger the PBO of First Screen and get the input's from user.

    Then it triggers the PAI of the First Screen. In PAI it have the Command like Call screen2.

    So It again triggers the PBO of the Second Screen.

    Thanks,

    Reward If Helpful.

    Understand that the PBO and PAI are part of the screen flow, so after round trip will do the PBO and PAI. So say you have a call screen in your program, it will fire the PBO, the screen will be displayed, and the user will do some interaction and press some FCODE, the PAI of that screen will then be fired. If the FCODE is not being handled in the PAI(or not redirecting to another screen), then the PBO of the current screen will be fired again, and the same screen displayed again, because this is all part of the "Round Trip" between the dynpro and the application. Make sense?
