there is no CLEAR SCREEN statement in ABAP as far as i know.

So you need tomanually clear all the fields on that screen in PBO. maybe you need some criteries to check cause there might be some cases where you dont want to clear your fields, tho i cant know that.

Hi,

Clear all fields in PBO of screen 100, can not clear in one go , as we don't have any control then.

Before you go back to screen 100 (with LEAVE TO SCREEN...) clear the screen fields. That should do the trick.

E.g.

CLEAR: screen100_field1, screen100_field2,... and so on.

LEAVE TO SCREEN 100.

Most simple way: define your screen fields in a structure and then clear the structure.

E.g.

data: begin of wa_screen100,
            field1,
            fielld2,
            and so on....
         end of wa_screen100.


clear wa_screen100.

Hi,

Generally we declare a single UI structure which consists of all the fields used in the screen.

data:wa type zuistructure.

name the screen fields like wa-field1,wa-field2 etc

clear wa. "I think this will clear all fields.

In the PBO part of screen 100.

include clear statements for all fields which you need to be blank when you return to screen 100.

for example :

clear wa_vbap-vbeln.

clear wa_vbap-posnr.

clear wa_vbap-cmpre.

hope this solves your problem..

Please check that in the "lay out" the set and get parameters, are not checked, other wise you cannot clear the values
