Migrations occur, for example, when a customer decides to host his systems at Rödl & Partner and the SAP systems therefore have to be migrated from in-house operation or from the original hosting provider to our data center. Also in the course of a conversion to S/4HANA, the data is migrated from the original database type to an SAP HANA database. This is also done with the tool "SUM" (Software Update Manager) via the so-called "DMO" (Database Migration Option).
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.

The SAP basis is often perceived as a brake within projects or when introducing new technologies. This is partly due to the late consultation of the SAP basis on the issues of technical feasibility as well as the integration of new technologies and applications into the existing system landscape. By implementing the recommendations, the SAP basis is repositioning itself in parts within the IT organisation. The SAP basis has a clearly defined self-understanding (inward-looking perception) as well as a clear positioning and a defined task area within the IT organisation (outward-facing perception), as shown in Figure 5. By integrating the SAP basis into the development of the IT strategy, the digitisation strategy and a clear communication with the CIO, the SAP basis has the opportunity to deal with technologies and topics at an early stage. As a result, the SAP basis is prepared for requests from business units or other IT departments and has the opportunity to approach them proactively. The SAP basis is supported by an IT service and IT product catalogue, which describes the scope of the SAP basis. For internal communication and communication with external service providers, as well as other suppliers, outsourcing partners or outsourcing partners and cloud service providers, there are up-to-date and meaningful documentation and process descriptions. For the control, measurement and monitoring of external partners, Service Level Agreements and meaningful key figures are also available.

A note box in which data of all kinds can be quickly filed and retrieved. This is what Scribble Papers promises. At first, the program looks very spartan. But once a small structure is in place, you realise the great flexibility of this little helper.
Always the latest version: Your system will always be up to date and you will have access to the latest versions. Patches are performed by the external SAP Basis team.
"Shortcut for SAP Systems" makes it easier and quicker to complete a number of SAP basis tasks.
You wanted to rush to release a transport order in the quality system of your SAP landscape and accidentally clicked on "Reject" instead of "Approve"? Now the order cannot be transported any further and will soon be cleared by job from the queue? Don't despair: In this blog post, I'm going to tell you a simple way to get rejected transportation to the production system anyway.
The buffer times are necessary because it is not possible to predict exactly how long a job will take to complete, since the duration depends on many incalculable parameters.
