Change it in the screen painter to a drop down list. If the domain of the field has fixed values, or a value table no other change should be required. However, if it does not then change the drop down list value source to be from program and then use function module VRM_SET_VALUES to provide the value list.

Drop down lists cannot accept free text and can only accept a valuue that exists in the value list therefore it will either be empty or contain a valid value.
