Basics SAP Authorizations including Fiori - Online Training
SAP Security Automation
The assignment of roles does not include any special features. Therefore, we only deal with the topics of time-space delimitation and logging. Time-space validation is implemented as an additional filter that runs after the usual permission checks. This additional filter logic works as follows: The first step is to check whether the user is entered in the tax verifier table (Table TPCUSERN, Configuration with the transaction TPC2). Only then will the further tests be carried out. If not, no additional checks will be carried out. The programme is then checked to see if it is included in the table of allowed programmes (table TPCPROG, configuration with the transaction TPC4). If the check is negative, the system cancels with a permission error. The time-space check is performed against the valid intervals in the table TPCDATA (configuration with the transaction TPC6). The time-space check works in context: In addition to the supporting documents of the audit period, older supporting documents are also included if they are still relevant for the audit period, such as open items that were booked in previous years but only settled in the audit period. Records that do not fall into the valid period according to the logic described above are filtered out.
The four important concepts of SAP security first require a certain amount of effort. They not only have to be coordinated, formulated and made available, but also continuously updated and, above all, actively implemented. Nevertheless, the return on investment is high, because they prepare for all eventualities, provide audit security, and also offer a high level of protection for the SAP system and thus for the company itself.

After you have completed the development of the User-Exit, you still need to transport your validation. To do this, navigate back and highlight the validation you have created. You can now include the objects in a transport order using the Validation > Transport menu path. Finally, you need to activate your validation via the OB28 transaction. Please note that this is only possible for one validation (with several steps if necessary) per booking circle and time. Now your validation will be carried out with additional checks during the document booking via an interface.
An essential aspect in the risk assessment of a development system is the type of data available there. Normally, at least a 3-system landscape is used (development, test and production system). One of the purposes of this is to ensure that (possibly external) developers do not have access to productive or production-related data. Since developers with the required developer authorizations have access to all data in all clients of the system concerned, there should be no production-related data in a development system. Even a division into a development and a test client (with the sensitive data) within the system does not protect against unauthorized data access for the reasons mentioned above. In the following, it is assumed that no production-related data exists on the development system. Otherwise, extended authorization checks must be carried out in the modules and access to production-related data must be approved beforehand with respect to the production system by the respective data owners. Since developers, as described, have quasi full authorization through their developer rights, revoking the authorizations listed below can raise the inhibition threshold for performing unauthorized activities, but ultimately cannot prevent them.
"Shortcut for SAP systems" is a tool that enables the assignment of authorizations even if the IdM system fails.

If an authorization system grows too much over the years and there is no structured approach, the result is uncontrolled growth.
The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.
Authorization tools are only as good as the person using them.
