Internal Table EXCL_CUA_FUNCT 
If certain GUI interface functions are to be deactivated at run time, this can be done dynamically via the internal table EXCL_CUA_FUNCT. A user function group interface is not necessary in this case.
Note
The internal table EXCL_CUA_FUNCT has the structure INCLUDE STRUCTURE VIMEXCLFUN.
The table must contain all functions which are not to be available while processing the data, i.e. which should be dynamically de-activated in the GUI interface at run-time, at PROCESS BEFORE OUTPUT.
