Customers with such a case regularly contact us. Creating a Permission Concept from the ground up is often a time-consuming task. Furthermore, the know-how, which aspects should be dealt with in an authorisation concept and how the corresponding processes can look practical and at the same time audit-proof is often lacking. Our solution: tool-based generation of an individual, written authorisation concept In this situation, we have recommended to our customers the tool-based generation of a written authorisation concept directly from the SAP system. We use the XAMS Security Architect tool, with which we have had good experiences. This includes a template for a revision-proof and comprehensible, written authorisation concept. It includes established best practices for role and entitlement management. The template covers all relevant areas in a permission concept. The included text of the authorisation concept is completely customisable, so that the concept can be tailored to your situation without creating a permission concept from scratch. Dynamically update the written authorisation concept One of the biggest challenges after the development of an authorisation concept is to keep it up to date in the long term and to measure the sustainable implementation in the system. This is achieved by integrating live data such as configuration settings and defined rules directly from the connected system. For example, lists of existing roles or user groups and tables are read from the system each time the document is generated and updated in the permission concept. The following screenshot shows an example of what the appearance in the concept document might look like. Automatically check and monitor compliance with the concept To check compliance with the concept, the XAMS Security Architect includes extensive inspection tools. These cover the rules formulated in the concept and are suitable for measuring the extent to which the reality in the system meets the requirements formulated in the concept.
At best, for the time in which an emergency user is in service, a separate log of the activities undertaken is written, which can then be evaluated. In the following chapter I would like to explain our best practice approach to implementing an emergency user concept. Our approach to using an emergency user concept We have had good experience with the use of the Xiting Authorizations Management Suite (XAMS) in this area. This suite consists of various modules for creating role concepts, managing permissions including a permission concept, and also enables the implementation of an emergency user concept. XAMS works here with a limited time assignment of reference users with extended privileges to enable the emergency user concept. A self-service application may be made with a justification and a period for allocating special rights. The application window is illustrated in an example in the following screenshot: Evaluation of the use of the Emergency User Concept Once this request has been initiated, a new mode will be opened for the user, in which he can work with the extended rights. In addition, depending on the configuration, a stored workflow can be initiated as an approval process, or pre-defined controllers will be notified by email to verify activities. Once the session has ended with the emergency user, the responsible persons will receive another email with the logged activity of the user with the extended permissions. One of these logs is shown in the next screenshot: These logs can also be viewed in the system. Here you will get an overview of all the sessions that have been run. In addition, it is possible to approve activities with special rights after an evaluation. This allows the controller to get an overview of the activities undertaken with the emergency user. If you are using this Emergency User Concept and following these steps, you can ensure: Each user on the production system retains his or her original necessary rights.

IMPORT_PROPER In this step, the repository and table entries are recorded. There are the following reasons that may lead to the termination of this step: TP_INTERFACE_FAILURE: Unable to call tp interface. TP_FAILURE: The tp programme could not be run. For more information, see the SLOG or ALOG log file. TP_STEP_FAILURE: A tp-Step could not be performed successfully. The cause of the error can be found in the appropriate protocol, for example in the import or generation protocol. If the generation (tp-Step G) is aborted, you can either fix the errors immediately or after the commit is completed. In the latter case, you must do the following: To ignore the generation errors, select Additions Ignore Gen Error. Continue the playback. Buffer synchronisation problems can also cause generation errors. For more information, see Note 40584.
This access method depends solely on the rights assigned to the user. System users: Users of this user group are comparable to SAP*. They act as administrator in the system. Therefore, they should be deactivated / set to inactive as soon as possible, as soon as the system operation is ensured. You should still be aware of the SAP ERP environment to address this security risk. In a HANA system, there are privileges instead of permissions. The difference is first of all in terms of terminology. Nevertheless, the permissions are assigned differently (directly / indirectly) via the assignment of roles. These are thus accumulations of privileges. As in older SAP systems, system users must be disabled and certain roles that already exist must be restricted. Compared to an SAP ERP system, small apps are allowed instead of large applications. In this case, attention should be paid to an individual authorisation. It should be a matter of course for users to have implemented secure password rules. Settings Securing the system also means securing the underlying infrastructure. Everything from the network to the host's operating system must be secured. When looking at the system landscape, it is striking that the new technology brings many connections that need to be secured. The SAP Gateway, which is responsible for the connection between backend and frontend, is also a security risk and must be considered. All security settings of existing and future components must be validated to HANA compatibility. Secure communication of connections is obtained when you restrict access where possible. Encryption of the data of a HANA system is disabled by default. Be sure to encrypt sensitive data anyway. Especially data that is archived. If an attack is made on your system, you should be able to run forensic analysis, so you should enable the audit log. Moreover, few users should have access to it.
