# Model-View-Presenter

**Model–view–presenter (MVP)** is a derivation of the model–view–controller (MVC) architectural pattern, and is used mostly for building user interfaces.

In MVP, the presenter assumes the functionality of the "middle-man". In MVP, all presentation logic is pushed to the presenter.

# Report structure

Create ABAP report, for example **ZTEST_ALV**, with few includes:

```abap

INCLUDE:

  ztest_alv_app_model,

  ztest_alv_app_view,

  ztest_alv_app_presenter,

  ztest_alv_app_top,

  ztest_alv_app_sel,

  ztest_alv_app_scr_0100.

```

# Screen

Create dynpro screen **0100** and place container **MAIN_CONTAINER** on it. 

![0100 Screen](/images/0100_screen.png)

Also you need to have GUI Status **0100** and GUI Title **0100**.

![0100 GUI Status](/images/0100_gui_status.png)

Add screen flow logic for this screen:

```abap

PROCESS BEFORE OUTPUT.

 MODULE STATUS_0100.

PROCESS AFTER INPUT.

 MODULE USER_COMMAND_0100.

 MODULE EXIT_USER_COMMAND_0100 AT EXIT-COMMAND.

 ```
