Generally SET parameter is used in PAI events to a screen. The user may have given some value for a field; once we check the accuracy of this value, we can use the SET parameter id in the PAI. The GET parameter is used in the PBO event. During PBO, the screen for display will be prepared for the users. On the screen, some fields must be filled with some default values.
