SY-UCOMM and OK_CODE

Hi All,

I have got a simple question that I would like to clarify. 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.

Regards,

Alex

Reason found in http://help.sap.com/saphelp_nw2004s/helpdata/en/9f/dbaa1335c111d1829f0000e829fbfe/content.htm.

"In your ABAP programs, you should work with the OK_CODE field instead of sy-ucomm. 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."
