Better technologies have expanded the role of SAP Basis Administrators, paralleling the IT industry as a whole. It's no longer enough to keep the system running and performing well. An SAP HANA Basis Administrator also plays a role in cost control, IT strategy and even business policy.
As an interface to the user, the presentation layer contains software components (the SAP GUI) by means of which the user is presented with the application. During its runtime, an SAP GUI component is always permanently linked to a user logon to the NetWeaver AS ABAP.

However, the system modifiability has no influence on customising changes that are customised by the client. If you want to set the customising changes to customise, you must go to the client control. You can achieve this either by pressing the button "Client Control" when changing the system or by calling the table T000 via the transaction SM30. If you are now in the list of clients, you can double-click on the respective row to jump into the settings of the respective client. Here you can also make the desired settings and save them. Step-by-Step Tutorials System Modifiability (Customising Settings and Repository Objects that are independent of the client) Call the SE06 and click on "System Modifiability". Adjust the desired objects and global setting, depending on your request. Save the changes. Client control (custom customising settings) Call the T000 table in the SM30.

User authentication is usually performed by entering a user name and password. This information is called user credentials and should only be known to the user, so that no third party can gain access to the system under a false identity. This post explains how a user's password protection can be circumvented and how to prevent it. SAP system legacy data The login data of a user, including password, are saved in the USR02 database table. However, the password is not in plain text, but encrypted as a hash value. For each user there are not only one but up to three generated password hashes. Different algorithms are used to calculate these values, but only the Salted SHA1 can be considered sufficiently safe. Table deduction USR02 The secure password hash is located in the fifth column of the pictured table deduction with the heading Password hash value. The corresponding data field in the column is called PWDSALTEDHASH. Weak Password Hash Risks You have a good and working permission concept that ensures that no processes or data can be manipulated or stolen. A potential attacker now has the ability to read out your database with the password hashes. The hash values are calculated using password crackers, which are available on the Internet at home, and the attacker now has a long list of user credentials. To damage your system, the user will now search for the appropriate permissions and perform the attack under a false identity. Identifying the actual attacker is virtually impossible. Check if your system is vulnerable too Your system generates the weak hash values if the login/password_downwards_compatibility profile parameter has an unequal value of 0.
