In report program, the function code will be assigned to both SY-UCOMM and OK_CODE field defined in the screen. I would like to know what's the purpose of making two different versions of the same value? Why shouldn't I access the sy-ucomm directly instead? If so, I can skip saving the OK_CODE to a temporary variable and clearing it up.</P><P></P><P>Regards,</P><P>Alex</P></BODY></HTML> Fri, 24 Apr 2009 08:36:24 GMT Former Member 2009-04-24T08:36:24Z SY-UCOMM and OK_CODE https://community.sap.com/t5/application-development-and-automation-discussions/sy-ucomm-and-ok-code/m-p/5530378#M1263522 <HTML><HEAD></HEAD><BODY><P>Hi All,</P><P></P><P>I have got a simple question that I would like to clarify.

There are two reasons for this: Firstly, the ABAP program has full control over fields declared within it, and secondly, you should never change the value of an ABAP system field."</P><P></P><P>Edited by: Alex Lau on Apr 24, 2009 10:38 AM</P></BODY></HTML> Fri, 24 Apr 2009 08:37:51 GMT https://community.sap.com/t5/application-development-and-automation-discussions/sy-ucomm-and-ok-code/m-p/5530379#M1263523 Former Member 2009-04-24T08:37:51Z
