While uploading SAPKB640011 I got the short dump and not allowing me to work. Short dump is as follows:
Syntax error in program "CL_GUI_FRONTEND_SERVICES=====CP"
Error in ABAP application program.
The current ABAP program "SAPLGRAP" had to be terminated because one of the statements could not be executed.
in the include "CL_GUI_FRONTEND_SERVICES=====CI" in line 25:
"Implementation missing for the method "IS_VALID_HANDLE"
Pls help me to resolve this.
