Process after enter. Code that is executed after a button at the screen has been pressed.

Q7. Can We Use Flow Logic Control Key Words In Abap/4 And Vice-versa?

The flow control of a dynpro consists of some statements that syntactically resemble ABAP/four statements .However, we can not use drift manage keywords in ABAP/four and vice-versa.

Q8. What Does Pai And Pbo Contain By Default?

PBO - MODULE STATUS_0100 - Key / button definitions

PAI - * MODULE USER_COMMAND_0100 How do you deal with the code in the back of the button that was pressed

Q9. What Is Dynpro? What Are Its Components?

A dynpro (Dynamic Program) includes a display screen and its float good judgment and controls exactly one conversation steps. The one of a kind components of the dynpro are:

Flow Logic: calls of the ABAP/four modules for a screen.

Screen layout: Positions of the text, fields, and pushbuttons and so on for a screenScreen Attributes: Number of the display screen, quantity of the subsequent screen, and others

Fields attributes: Definition of the attributes of the individual fields on a display.

Q10. How Can I Identify Which Button Is Pressed?

Q14. How Does The Interaction Between The Dynpro And The Abap/4 Modules Take Place?

A transaction is a group of screens and ABAP/four workouts, managed and finished by using a Dialog processor. 

The Dialog processor tactics screen after the display screen, thereby triggering the correct ABAP/four processing of each display screen .

For every display, the gadget executes the glide good judgment that consists of the corresponding ABAP/four processing. 

The manipulate passes from screen float good judgment to ABAP/four code and back.

Q17. How Are The Function Codes Handled In Flow Logic?

When the User selects a function in a transaction ,the system copies the feature code into a particularly distinct gadget discipline known as SY-UCOMM.

This discipline is Global in ABAP/4 Module Pool.The F-CODE can then be evaluated within the corresponding PAI module. 

The characteristic code is always handed in precisely the same way, no matter whether or not it comes from a screen push button, a menu choice, feature key or other GUI element.

Q18. Difference Between The Normal Report / Program And Module Pool Program?
