once tcode is executed PBO will be executed just before the screen output.

after you fill in values and execute again it takes input values and PAI is executed next PBO and then next screen.

Cycle goes on this way.

TCODE->PBO->screen1->PAI->PBO->screen2->PAI->PBO->screen3.

Hi,

In case of module its always PBO that gets trigger first and then PAI.

That the reason why its call PBO which stands for Process Before Output and PAI -> Process After Input

hi,

On executing the transaction PBO is triggered and we see the screen.

Once a user action is initiated in the screen PAI is trigerred and the ok code is populated with the function code.

Hi,

PBO triggers first then PAI.

then again PBO..pai..

PBO-process before output-is triggered before displaying the screen.it transfers the dta from program to screen..

PAI-Process after input-is triggered after the user interacts with screen.it transfers data from the screen to program.
