SWU2 Transactional RFC
SAP Basis Support & Monitoring
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 HANA has been one of the major topics in the SAP environment for the last few years. Many customers are currently faced with the question of whether or not to migrate your SAP system. In addition to the actual changeover itself, there are many other topics on which you should have already informed yourself in advance, as these influence the success of SAP HANA in your company. What do you already know about SAP HANA? I would like to encourage you to think about security in the following article. If you would like to learn about the architecture of HANA, I recommend a contribution from our colleagues at erlebe Software. SAP HANA Scenario But why are we even talking about HANA Security? Why is it so important to consider new security strategies with the new technology? With HANA it is possible to analyse data quickly. BW scenarios primarily benefit from the in-memory database (IMDB) used, as speed advantages in data access are particularly positive. Compared to a classic ERP / R3 scenario, the normal DB is replaced by HANA. The desired speed advantages result. However, migration is expected to be required for the changeover. This is caused by customer-specific developments in the system. HANA is not a further development of SAP ERP, HANA is the next stage of an ERP system. It is well known that an ERP system contains the capital of the companies. Therefore a new HANA system like all other ERP systems is also interesting for attackers. On the one hand, such a system contains the critical business data that are available for espionage. In addition, most business processes are mapped in such a system and offer an attack surface for sabotage. In addition, users do not initially know the new technology well. This also applies to administrators in the area of a new technology. Attackers quickly gain a dangerous leap of knowledge over these user groups. SAP HANA has a lot of new features, although many existing ones are used by SAP ERP, so there is a risk here.
What has changed in the past decade and what can we expect in the coming decade? How will they affect the requirements profile of SAP Basis experts and how can they adapt to them?
Soft skills in particular also play an important role in this job description. Communication skills are very much in demand on a day-to-day basis, because SAP administrators are often in close contact with customers and have to respond to their wishes and questions. They also need the ability to work in a structured manner and to find creative solutions and decisions. Continuous training in the field is advisable in order not to lose touch.
SAP Basis Administration Batch Control Job Control A large proportion of batch jobs run at night, while IT systems are available for dialog and online applications during the day. Meanwhile, web applications demand computer capacity around the clock. Even dialog systems are no longer in operation only from 8 a.m. to 6 p.m., but between 7 a.m. and 10 p.m. or longer. The time window for administration tasks is increasingly shifting toward transaction processing. This leaves less and less time for mission-critical batches, which can lead to disruptions and terminations. Whereas batch processing used to be a mainframe domain, companies today usually have to control background processing in heterogeneous operating system environments and client-server applications. For this reason, cross-platform, integration-capable job schedulers that can respond to unplanned events are in demand.
"Shortcut for SAP Systems" simplifies tasks in the area of the SAP basis and complements missing functions of the standard.
In addition to purely administrative tasks, SAP administrators are also responsible for communication tasks.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
Ignore error in SPAM steps If an error is detected in one step, the transaction SPAM stops processing until the error is resolved.
