How does a blockchain build consensus? Once you decide to send a payment to someone, you must use the Private Key to "sign" it (in German: signature). This means nothing other than that you specify another public address to which you want to send the money and confirm this transaction with your own private key. You don't have a central authority to send the information to, you're going to spread the information to all the other Miners around you. The miners then forward this information to other miners, who in turn do the same. This exponential wave of information reaches the entire network of the distributed community within a few milliseconds. Every time a miner receives a transaction, it checks that the transaction is actually correct. It checks which private key has signed, which public address the transaction should go to and whether the sender has enough "coins" for this transaction. What are consensus mechanisms? Any miner that solves a transaction through complex mathematical calculations is rewarded by the sender with a "fee" (transaction fee). How will it be decided which miner will receive the transaction fee? Because only one can get this reward. Also, what happens when you try a double spending by sending one transaction to one miner and then another transaction with the same money to another one millisecond later? These two could not yet exchange and thus information would be different in the network.
To configure the SAL, please use transaction RSAU_CONFIG (formerly SM19) as of SAP Release 7.50. It is recommended to activate the cross-user logging with minimum settings and to record all audit classes for users with extensive authorizations, such as SAP standard and emergency users. These settings should always be configured on a cross-client basis.
In order for Fiori applications to be displayed according to the calling users, appropriate Fiori permissions must be maintained in the PFCG. There are several points to consider. This article discusses the permissions required to launch a Fiori application. In addition, a short explanation is given, how the displayed tiles can be configured in the Fiori launchpad via reels. To run Fiori applications from the launchpad and the permission queries defined in the OData services, the corresponding Fiori permission objects must also be maintained in the PFCG. Here the start permissions for the application's OData service in the backend system as well as permission objects are relevant for the business logic of the OData services used in the application. In general, it is important to know that if Fiori is implemented correctly, permissions must be maintained in the front-end server (call Launchpad, start the tile, etc.) as well as permissions in the back-end server (call the OData services from the backend). This article explains this in more detail.
When I began my career administering SAP ERP on Oracle in the early 1990s, running a database required far more knowledge. An Oracle administration expert with a decade of experience understood perhaps only about 5% of what the database required.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
These are two relatively simple examples of Security Check tools' rulebook.
In addition, the SAP Basis team can easily implement new functionality in the new system - without compromising the security, stability or quality of the previous function, which would be the case with non-certified and inexperienced people.
