How to validate a user name so that it can accept only alphabates....?? no digits...

You don't need the UPPER CASE bit, since the parameter has not been defined as allowing lower case.

The system variable sy-abcde contains the alphabet in uppercase.

PARAMETERS: P_NAME type sy-uname.

IF NOT p_name CO sy-abcde.
  MESSAGE 'ENTER ONLY ALPHABETIC CHARACTERS' TYPE 'E'.
ENDIF.

AT SELECTION-SCREEN ON P_UNAME.

IF P_UNAME CA '0123456789'.

MESSAGE 'ENTER ONLY ALPHABATES' TYPE 'E'.

ENDIF.
