Unit 9: Scheduling Background Tasks ADM100
Figure 107: Using External Programs
External commands are host system commands or programs predefined in
the SAP system by an administrator. They are protected by authorizations
so that normal users can only schedule the commands for which the
system administrator has assigned them the authorization. You can
therefore provide functions outside the SAP system, at operating system
level, for users of the SAP system.
External programs are unrestricted commands that are neither predefined
nor restricted by authorizations. A user with administration authorization
can enter any external program in a job step. No SAP authorization check
is performed before the execution of the command. External programs
provide an administrator (user with administration authorization for
external commands (Authorization object S_RZL_ADM: Background
Processing: Background Administrator)) the flexibility to run any
required host system command in the SAP system without administrative
preparation.
