In order to make a transaction in cryptocurrencies, you do not have to let your bank know about it as you would for "normal" money, but you have to use the Private Key to prove that you own the coins. The transaction looks like a piece of the puzzle. Half of the puzzle piece consists of information about the coin set, time and public address of the sender or receiver. The other half is the signature of the private key belonging to the sent public address. Both halves make this piece unique. Changing only one piece of information would completely change the whole transaction or the appearance of the puzzle piece. This transaction is transferred to the network or to the miner and is checked for correctness first. If everything fits, the transaction will be sent to other miners who will do the same. Otherwise, the transaction is ignored. Miners try to integrate the transactions into a block. This is called mining and we have described it so that the miners put the puzzle pieces together into a puzzle (block). A small part of a block to be integrated follows from the block that was previously mined. If all miners accept the correctness of a completed block, they will all work the next one immediately. The puzzle (block) is fixed and is irrevocably connected to the block before or after. The blocks form a chain and are called blockchain, which contains all the transactions that have ever been made and is visible and unchangeable by everyone. In doing so, blockchain replaces a central institution and avoids double-spending, which ultimately gives value to a cryptocurrency. Smart Contracts The biggest advance compared to Bitcoin and similar applications is that second-generation blockchains, such as Ethereum, use the so-called Turing-Complete script language Solidity. This enables calculations to be made within the blockchain. While Bitcoin allows only rudimentary multi-signature functions, Ethereum opens the door to much more complex operations called smart contracts. Smart contracts are contracts in which a decentralised blockchain ensures their unchangeability and execution.

SAP Basis consulting can start with general consulting on SAP deployment and installation and configuration. In addition, the SAP consulting can transition to an external takeover of updates and upgrades of SAP components or even the complete takeover of the administration of the SAP system.
Performance tuning
Planning ahead: Ideally, your SAP system administrator should make the necessary adjustments to your system landscape before end users are affected. This requires careful planning and anticipation of long-term trends.

What are the requirements and benefits of a modern identity management system (IDM) in the GRContext and what should be taken into account in application processes? Modern companies need to be able to effectively control their employees' access and system permissions to ensure optimal corporate control and monitoring. This need can also be inferred from legal requirements. IDM is the user and permission management within an organisation. These systems are an essential part of the internal control system. This includes the continuous monitoring and allocation of access possibilities as well as the systematic securing of functional separation (SoD - Segregation of Duties) in the IT systems. This is primarily intended to better manage relevant business and financial risks and to prevent criminal acts. The management of user and permission structures must ensure that, when the roles and responsibilities change, the privileges of the employees concerned in the systems are adjusted. Failure to do so will result in a multi-department employee having extensive privileges that can be critical in combination. Trust is good, control is better In order to avoid employees being entitled beyond your area of competence, user data and permissions must be continuously adjusted to the current requirements. It therefore makes sense to regularly carry out a recertification process in which the role owner and the manager sign off in compliance with the four-eye principle that the employee is entitled to the current privileges or may have to be deprived of rights from previous activities. Provisioning as a central function of the IDM Provisioning components form a central function of IDM systems, which provide users with individual access rights for the required IT resources according to their task.

With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.

These can be found in the RSBASIDOC source system connection table Field Description I_BIW_LOGSYS The logical name of the BW system.
