STANDARDISATION & AUTOMATION
Will Blockchain's Economy and Administration Revolutionise? What is a blockchain? A blockchain is a complete and unchanging transaction history of all transactions of a decentralised community that everyone who is part of it agrees to. The word blockchain first fell in connection with Bitcoin as a decentralised network for payments in the digital currency of the same name. The blockchain describes an underlying technology in which all transactions are publicly and unchangeably recorded. This transaction history is updated periodically. Each participant in the decentralised community accepts it as a reality, stores it on their computer, and can thus ensure at any time that no one can duplicate expenditure, as this would lead to a conflict in the transaction history elsewhere. A peculiarity of blockchain technology is that it has solved the "Double Spending Problem". Double-spending means something that can be doubled, and by 2008, only one central institution was considered to be sustainable. Double Spending can best be understood using the example of an image on a mobile phone. When I upload it to Facebook, I made a copy of it and I can upload it to Instagram, for example. So I used my picture "double". This effect made it impossible to establish a trustworthy, decentralised digital currency by 2008.
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.
SAP Emergency User Concept - How it works and how it works
Critical business processes require a secure, efficient and stable operation of an SAP system landscape. High demands on the management as well as the operation of the underlying SAP NetWeaver platform require competent support in all tasks of planning, support and updating of the SAP Basis. The increase in installed components as well as systems integrated via interfaces expands these needs. Only with professional care and maintenance of its components can SAP NetWeaver bring its advantages as an integrative platform to bear.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.
Among other things, it determines which application server a user logs on to in order to distribute the workload (load balancing). The message server also enables the individual application servers to communicate with each other.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.

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.
This includes several possible implementation variants: for example, SAP GUI for HTML (Web GUI) and Web Dynpro for ABAP (WDA).
