The AUTHORITY-CHECK

Statement

AUTHORITY-CHECK OBJECT ‘S_DEVELOP’
ID ‘DEVCLASS’ FIELD

‘YLJS’
                                    ID ‘OBJTYPE’    DUMMY
                                    ID ‘OBJNAME’   DUMMY
                                    ID ‘P_GROUP’   DUMMY
                                    ID ‘ACTVT’         ‘03’.

The option DUMMY
suppresses the check
for
the specified field. The
net
effect is that the user
can
perform any activity on
development class YLJS.

The AUTHORITY-CHECK
lists the fields to be
checked and verifies
what the user is
attempting to do
against what the user is
authorized to do.
