You have 2 Requirements.

1. Default value should be 1.

Write the code in PBO event Module init_screen.

MODULE init_screen.

ZFIELD = '1'.

ENDMODULE.

2. Validation for the value should be between 2-9.

Write the code in PAI.

Hi Niraj

In your PAI logic, please add this code

FIELD field_name VALUES (between '2' and '9').

Where field_name is your screen field name which you want to validate.
