But I am getting message invalid field format (screen error) can any one tell me why I am not able to run the seletion screen when I am using input/output field, also please let me know how to solve this problem.
The field which you want display on screen how you have defined in top-include of program..?? or r u refering directly to Standard table.
If the field in say of type INT4 & in Layout Editor (Screen Painter) if you change the type of field, this error will appear.
Make sure that you have not changed the properties of field in screen layout.!!
