Defaulting Field Values

Method #1

Method #2

Method #3

PBO Module: Before the screen is displayed to

the user ,assign values to screen fields

Parameter Ids: For ABAP Dictionary fields using

SET/GET PARAMETER ID ABAP statement or

SPA/GPA field attributes

Hold Data: Use Hold Data function for the screen

You can check the GPA

field attribute instead ofcoding the GETPARAMETER ID

statement in aPBO module.

You can check the SPA fieldattribute instead of coding the

Summary

You can set default values for screen fields using three methods:In a PBO module

Assign values to screen fields using Parameter IDs for ABAP Dictionary fields

Use Hold Data function for the screen.

By default, the cursor will be positioned in the first field open for input on a

screen. You can change this position two ways: Set the cursor position in the Screen Attributes

Use the SET CURSOR FIELD ABAP statement in a PBO module.
