Hi,

Check below code.

In this method we set the value list attribute to 'A'.The value list will be filled in the PBO by using FM VRM_SET_VALUES .

TYPE-POOLS : VRM

DATA : field_id TYPE VRM_ID ,

values TYPE VRM_VALUES,

value LIKE LINE OF values.

PROCESS BEFORE OUTPUT

MODULE list_fill_100

MODULE list_fill_100 OUTPUT

SELECT f1 f2 f3 FROM tab WHERE condition.

value-KEY = f1.

value-TEXT = f2

APPEND value TO VALUES

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'i/o screen field'

values = values.

ENDMODULE.
