Dialog Step
A dialog step is a SAP R/3 screen, which is represented
by a dynpro. A dynpro, or dynamic program, consists of a screen and
all the associated processing logic. It contains field definitions, screen layout,
validation and processing logic, and so forth. A dialog step is controlled exactly
by a dynpro.
The processing logic means that the dynpro controls what
has to be done before the screen is displayed (process before output or PBO) and
what has to be done after the user finishes entering information (process after
input or PAI).
When users are navigating in the SAP R/3 system from screen
to screen, they are actually making dialog steps. A set of dialog steps makes up
a transaction.
