After installation SAP create 2 default users SAP* and DDIC can anyone tell me what is the difference between these two users? I mean I want to know the following:
Thanks in advance!
DDIC is the maintenance user for the ABAP Dictionary and software logistics. DDIC is the only user that is allowed to log on to the SAP System during an upgrade. To secure DDIC against unauthorized use, you must change the initial password for the user in clients 000 and 001 in your R/3 System.
The SAP System superuser, SAP* has by default the password PASS,To secure SAP* against misuse, you should at least change its password from the standard PASS. For security reasons, SAP recommends that you deactivate SAP* and define your own superuser.
